Ask HN: What are your best purchases under $100?
35 points by krishadi 7 hours ago | hide | past | favorite | 125 comments
Curious what items under $100 have made your life better or any meaningful impact.

Revival of this [thread](https://news.ycombinator.com/item?id=23363396) from 6 years ago. Thought it would be fun to have new answers to this :)





A 10 foot USB C cable. It reaches anywhere in the room. I can charge my phone in any position in bed. I only recently 'splurged' on this $10 item and it is the best thing ever.

Seconding this. Dumbest, most obviously useful thing, yet we never think to buy one. My wife and I have our own now.

I like this question because I come at it from a very different lifestyle. I’m a digital nomad and I have mostly lived out of a backpack and carry on for the past 10 years. My philosophy is that things have to be worth carrying and they should be very easily replaceable if anything gets lost, stolen or breaks. A few of my under $100 favs:

Universal GaN travel adapter: One of those square bricks that converts from any AC outlet to any AC outlet and has 3 or 4 USB charging ports built in. I got enough wattage to charge my usb-c laptop as well, so one brick takes care of all my devices.

Backup android phone: Our phones are so critical that I keep a hot swappable spare phone on me, currently a Moto G 2025. It’s already logged into all my apps and 2FA. I could throw my iPhone into the Seine and keep on trucking. It even has backup NFC credit cards. I keep a cheap travel eSim plan active on it so that if I am somewhere sketchy I can leave my main phone at home.

Logitech MX Keys Mini: Great portable keyboard. Backlit, usb c and multi-device. Typing this post out on my phone now.

GL-iNet Beryl: The do anything travel VPN router running OpenWRT out of the box. Great for securing and extending sketchy WiFi connections or if you have to work off your phone’s hotspot all day.

Decathalon Quecha Escape 500 23L: Such a great personal item size backpack for the price, less than 40 euros.


Great list (totally agree with backup phone). I now want to know your 100+ gadgets

This is a fantastic, fantastic backpack. I use it when flying and it fits perfectly in the Ryanair & co limits. I took one for each of my kids and all together we pack everything needed for a week+.

Isn't Ryanair limit more like 40l?

This is a personal item size bag for under the seat. The max size on Ryanair is 24 liters. You are thinking of the cabin bag which is more like 44 liters. This Decathlon bag is great because it maxes out the personal item size really optimally.

Aeropress coffee maker. Look up the James Hoffmann recipe on YouTube and you can never drink another coffee style again

I’ve tried most of the coffee making tools and fads, including the above mentioned recipe. I’ve spent thousands and hours and hours of time chasing the feeling others like you describe.

It was so easy for me to go back to a cheap drip coffee maker and pre-ground coffee. I realized that I’ll never appreciate the flavors and process as much as the investment would call for.


Aeropress is great. If you like a large mug of coffee have a try of the Clever Dripper. Had Aeropress at home and CD at work and eventually bought a CD for home because it’s so good.

Love the clever dripper So simple but so easy to repeatedly make a great cup of coffee.

It's even better with a "AeroPress Flow Control Filter Cap". No dripping, no inversion, and a little extra resistance improves the cup (I think).

You can also insert the plunger a small amount (maybe half an inch or so, if that) and pull it back up a tiny bit for a similar effect.

Rechargable, motion sensing led strips for inside my wardrobe. Not a big thing but improved my ability to find things no-end. The only issue is they don't turn on when it is light enough to see and we slightly disagree on how light that is.

Ceramic head tweezers. ~$3 on AliExpress, indispensable for some tasks.

An import die grinder that cost about the same as a new power switch for my Dremel. More powerful, better speed control, better chuck.

The dirt cheap rechargable die grinders. Noisy, not much torque, but cheap enough that you can have a few lying around for odd-jobs. Their low power also means they lack the ability to completely destroy your work in 0.3 seconds. Whereas the one mentioned above managed to shear off a shaft spinning in air when I accidentally turned it up instead of off.

Generaly replacing anything AAA powered by rechargable USBc


What's the brand of LED strip? I got several battery-powered motion sensor LED bars on AliExpress for use in closets. After the first charge they lasted maybe three weeks, then they rapidly faded, and no longer last more than maybe a day, so I've taken them out. I'm curious to hear if there are high quality versions, maybe something that can run off regular AA or AAA batteries so they can be changed when they inevitably burn out.

Speaking of tweezers on AliExpress: I love my $5.99 nail clippers that collect the clippings in a small compartment so they don't fly off everywhere. Super solid stainless steel construction that's considerably nicer than the cheap classic clippers I already had; it it had "Swiss made" on it or something I would have believed them. The ones I found are in a store called OURINER, but there are lots of weird brands making the same thing.


I just selected a bunch on AliExpress. Some were microUSB some were USBC. Some were a bit temperamental about charging. I usually take that approach with the really cheap items getting things from multiple suppliers so that at least one works. In general the worst I have received is poor quality items, nothing completely broken or fake yet*

I got two seemingly identical super bright panels and one now emits only 5% of the light. They look the same, have been run in the same conditions (and indeed the same housing now) run parallel off the same source. The other one is as bright as when I got it. Maybe one dodgy LED bringing the team down? I'm not yet skilled enough to diagnose problems like that.

*except for the time the store sent me a message to say I should cancel the order because they ran out. I couldn't find anywhere in the ever changing AliExpress user interface to cancel the item, so they sent me an allen key, I logged it as "item not as described" and they paid the refund.


Second the rechargeable motion sensing led strips! Dime a dozen on Ali Express. I have them in all the hallways in my house, garden shed, at the front door so I am not fumbling with my keys in the dark. If you mount them with the supplied adhesive magnets you can take them with you as a torch, feels like you are using a minecraft torch.

An old, pre-online activation copy of Photoshop that I still use today.

I was a very heavy photoshop user for ~20 years.

These days I just use photopea for when I need to make a small edit. It suffices for 95% of what I need to do.


I think I'm still using a version that was on a magazine coverdisk that was weirdly distributed as a full-version freebie to advertise the release of the all new lock-in edition.

Shoehorn!

Particularly a long one if you'd like to avoid bending down at all when putting on slip-ons. Of course they are primarily great for saving the backs of your shoes. The IKEA one is perfect (at least for 6'1" me).


STEEL long shoehorns.

Once you break one, you'll spend the money.


Yes, good callout! The one from IKEA is metal (usually not an IKEA fan but some good stuff like this and it's under $100, but of course there are tons of other options).

wood is better, it doesn't bend

Im having alot of fun with my new RTL-SDR dongle and Baofeng radio. I pretty quickly found SDR++ which really deepend the rabbit hole and generated about 1000 new questions.

A few weeks ago I knew nothing about radio or ham, but im learning alot and having fun. Its been a good distraction from "stuff".


probably one of those super bright one AAA battery keychain flashlights (~$12). Because its attached to your keys you always have it with you, and the smaller and brighter flashlights get, the more useful they become somehow. I'm not kidding, these things are blindingly bright.

Seki Edge nail clippers.

They're just so much sharper and more pleasant to use than your average drug store nail clippers, you can really feel the quality. I can barely stand regular nail clippers now.


$50 RTLSDR Kit

https://www.amazon.com/dp/B0CD7558GT

I got this to play around with what's on the air, and now I'm a full blown extra.


What's a full blown extra. I have wanted to pull the trigger on this for a while.

Ham radio Amateur Extra. The license after Technician and then General.

The RTLSDR is an easy way to see if you'd like radio or not.


Some of my best purchases were outdoor clothing I bought some 7 years ago on a whim. I constantly regret not getting some 10 of them, and sadly they don't make these anymore.

- Thermal inner pants from Berghaus - Knitted thermal jacket from Salewa


A backpod.

I had periscapular pain when sitting/standing for years: no pain in the morning, but it would grow during the day.

My backpod mobilises some stiff thoracic ribs, allowing me to then do exercises through that normal range of motion to strengthen it.


Smartwool shirt and socks. no odor absorption so ability to wear without daily washing. Good thermal regulation as well.

+1 to wool undergarments.

I prefer Unbound Merino to Smartwool for shirts, though Smartwool's socks are better than Unbound.


How do Darn Toughs compare? I've managed to wear through 8 pairs of costco wool socks without loosing any, so the idea of a lifetime warranty sounds promising.

I cover thousands of miles a year on my feet. Darn Tough socks live up to the name. I've never put a single hole in them. I've torn up socks from most other brands in a few hundred miles.

Darntough socks last much longer than smartwool for me.

How itchy do those get?

Less ichy than cotton

These really are amazing! I went full smartwool after getting a pair for hiking. I never looked back!

A £20 USB microphone from Aliexpress. The audio quality is so much better than laptop or headphone microphone

- darn tough socks https://www.amazon.com/dp/B000XG34G8

merino wool, always good temp and dry winter or summer

- fiskars shop scissors https://www.amazon.com/dp/B000VYOISU

cuts through stuff forever, easily, no slip etc

- 3-in-1 cables https://www.amazon.com/dp/B07R3R7QDL

(various brands) these make travel easy

You can also do 4-in-1 with usb-a/usb-c


A travel magsafe stand for flights has been really nice. Here's the one I have, but there's lots of options: https://a.co/d/18k9eCa

I use it with both my phone and also the Steam Deck (with a magsafe sticker). Obviously I could use either device just holding them, but it's more relaxing to do it this way.


Sleep buds (flat earbuds you can lie comfortably in). Mine were dirt cheap ones built in to sleeping mask off eBay. Def helped my sleep patterns when I started using Audible on a 30 minute sleep timer with them.

Kindle. Reawakened my inner book-worm many years ago. Library in a pocket. Don't use it so much tho since Audible.

Good quality (sturdy and high lumen) compact tactical torch.


Are you talking about Bose Sleepbuds or Oslo Sleepbuds?

Stanley Classic Legendary Vacuum Bottle 1.0 qt Bialetti Moka Express 6-Cup Aluminum Stovetop Espresso Maker

It's not about the time and money I saved by not having to go to a cafe, its about having a great supply of coffee available for the day.


My latest favorite gadget is a Wuben G5 light. Very compact, very bright, and has lots of handy features like a swivel and magnet. $20 on Amazon right now.

I have 3 for myself as I like to keep them around the house. I've also bought a couple as gifts for my sons who both really liked them.


I bought one a while back and I want to like it, but it's always turning off right when I need it.

The sliding switch on the side needs more resistance. I bump it accidentally, or it slides itself.

Could be some user error involved.

There's a lot to like about it, otherwise.


The work sharp precision knife sharpener.

I got tired of dealing with wet stones and having to soak them and get the right angle.

This sharpener can sharpen a chef knife razor sharp in less than 5 minutes.


Which model?

Can you adjust the angle for different knives? I have one of these in my cart.

4 of my 6 animals, which were free. (3 cats, 1 dog) Another was less than $200.

The other one I paid full price for (Miniature Dachshund), and he's an absolute money pit and brings all the drama.

No, we don't have any kids, why do you ask? :-)


Pocket operators are really fun to play with when you need a break from work.

Wow that looks like a cool purchase are they fun to play with like do you get to create your own beats

Very fun, you can make loads of things https://www.youtube.com/watch?v=TBOHsKv_ej8 - but mostly it's just something taxing to change the brain channel for me!

What is a pocket operator? Got a link?

These are pocket operators: https://www.youtube.com/watch?v=IhFIUdICYSA

They can be used on their own or together, frustrating, fiddly, fun. :)


Thermal underwear. Entering the 10th year of a 30 euro Helly Hansen long underpants that keeps me warm half the year.

Raspberry Pi 4 that served as my daily driver for around three years.

A couple of dumbbells that got me started with weight training, and kept me going during covid. Together with the basic equipment that I later bought, it saved me hundreds and hundreds of euros in gym memberships.

Best purchase under 10 euros is a simple cube with blank memo notes, that I use for grocery shopping and all kinds of other to do lists.


A set of Wera lasertip screwdrivers.

Or, a Knipex Cobra pair of pliers.


I feel like I get a ton of value out of a cheap VPS.

Just having a dedicated IP I can serve small and dumb things from has been fantastic, doubly so now that LLMs can do most of the driving.

https://lowendbox.com/ has a ton of providers, but I personally use vultr (no high or low praise for vultr, but they've been solid and cheap).


Azumaya brand kotatsu futons are now my favorite blankets for both sleeping and using around the house, and some of them at least are around $100.

They're fairly thick and very comfortable blankets, I love these way more than any other blankets we have (and we own quite a few different kinds). I'm seriously considering trying out other kotatsu blanket brands too, even the really expensive ones.


Leatherman skeletool knife. Small, rugged, has just the right number of tools on it. I’ve had one for about ten years and it goes in my pocket every day. The one time I managed to break the pliers on it by abusing them really badly, Leatherman replaced the tool under warranty no questions asked.

[EDJY](https://edjy.com/products/edjy-fingernail-cutter) nail trimmers have been awesome and I will probably only ever use that from now on

Probably some wood working tool, guess if I had to pick it would be my ECE Wedge set smooth plane since it is my most used tool by a long shot and it taught me a great deal about using planes.

I'm actually jealous of the people that have answers to this questions because I can't come up with any answer even if you multiplied the amount by a 1000.

For work: Vertical Ergonomic Optical Mouse, Anti fatigue mat

For home: Bidet

For personal: Kindle


How's your experience has been with the mouse

It's been fantastic. The mouse puts my hand in a natural "handshake" position, which has cut down on the wrist strain I used to get after long hours of work or browsing.

I'd highly recommend giving it a shot.


Appreciate everyone adding links to their suggestions!

Merino wool shirts, undergarments, hats.

Leather gloves.

Bedtime story books.

TwelveSouth Airfly pro airplane bluetooth sound adapter.

Belkin wireless car charger.

Standalone coat racks for the office.


magnetic shelving for the side of the fridge greatly expanded upon the cabinet space usable to me as a shorter person.

Custom motorcycle handlebar ends and levers. Cumulatively ~$80 and makes my riding experience drastically better.

I commute by bike daily, and I got some ergonomic handlebar ends and they've drastically improved by experience.

Chi-fi IEMs. People have no idea what sound quality can be achieved under 100$.

One of those reoriented vertical Logitech mice that reduce wrist pain. Amazing!

Similarly, and also right at $99.99: Evoluent VerticalMouse https://evoshop.biz/evoluent-verticalmouse-medium-p-72.html

Wow. A single picture of the product. And a name. And a price. That website went all-out on their minimalist design principles.

I use a Logitech MX Ergo that has a trackball, and it's helped me a lot with wrist pain. Using a trackball felt a bit weird initially.

I got "fashion shamed" by another geek for using a trackball "like it's still the 90s".

I don't put much stock in anything they've ever said, since.


And yet was the most common thing in the 90's.

Rivalism at its best. Removing the track balls before the next class got in to the computer room. That then escalated to fork bombing.

The IT techs got pissed that they glued shut the plastic release twist hatch.

Nesting silicone bowls with lids. Quiet and good for everything.

I want to use silicone bowls and lids, but silicone dishes always come out sticky and cloudy out of the dishwasher (even with rinse aid, whole house filtered water and extra rinse/wash cycles). Other dishes don't have this problem. What's your secrete for this?

Ergodriven topo standing desk mat - $99

Deltahub carpio 2.0 wrist rest - $35


gotta be a tire inflater (not sure what brand) that came with a flash light and works rain or snow powered by car adapter

Be careful buying those, and test them on multiple tires IMMEDIATELY.

I bought a series from Slime brand; every one failed within two tire inflates. Went to Harbor Freight, and bought their most expensive one; it has earned the price since (still under $100).


Someone gifted me one about ten years ago. I've had to replace the plug end, but the compressor still runs great.

It's saved my butt many times.

Mine is viaair, and the device is dedicated (no flashlight etc)


Project Farm on Youtube for the best reviews of items like tire inflators:

Walmart $22 pump - difficult to put on the valve stem but pumps OK. Beats a bicycle pump!

A no name Espresso machine. I got it as a gift but I doubt it was much more than $100. It works great. I had always assumed I would regret not buying a super expensive one, but it turns out you can have great espresso for not much money.

You can have great espresso for cheap(er) but $100 seems suspiciously low. Manual espresso is about the best bang for you buck possible, but that stretches to $200 or more depending on how fancy you want to get.

I would _love_ to know what espresso machine can be had for less than $100.

I had a $400 espresso machine but finally I'm just using my $50 moka pot. It's way easier and I like the flavour more.

This is what I have. It's not less than $100, but not much more:

https://www.amazon.com/dp/B0DP1WXVK8?&linkCode=sl1&tag=lydan...


Than you.

A good burr coffee grinder.

For less than $100!? Do tell, my friend.

I think _good_ depends on your expectations. We have the eureka mignon hacked with a bigger dial and custom burs. Still not amazing consistency. Looking to upgrade in the next few years.

Helikon-Tex Camp Hand Coffee Grinder is 35€ all-metal beast.

Swiss Army knife

Yep same for me. The knife you can take anywhere without alarming people.

Nicely made and always useful.


I'd nursed a foot callus for years that hurt badly when I walked barefoot. Weeks ago, sitting on the locker room bench, I hit my limit. In desperation I pulled out my pocket knife to do some field surgery. A few minutes into it I glanced up to see two guys sitting across the room staring at me open-eyed as I dug into my foot with the tip of that pointy knife (8.5" with 3.5" blade)! I just smiled and dug that sucker out.

Should have gone after that callus a year ago! Amazing how such a tiny thing can aggravate.

But you're right about a knife alarming people. Years ago in another life I opened a similar knife to cut a cable and my boss literally jumped backward and exclaimed in fear. But he came from a place where, when someone pulls out a knife someone else usually gets stabbed.


I use my knife like a fidget toy. Not usually in public, but one time a sales guy came in and it was just me and him. He's basically a friend.

I flipped the knife out and his eyes got huge, his arms went out sideways and he got in a football stance.

After he calmed down, he told me he was actually attacked with a knife when he was a kid.

Not long after, I finally wore out the fastener on that knife (a buck). Luckily I had already bought a twin for backup.


> staring at me open-eyed

They were probably just envious you were rocking a Kershaw Iridium Dessert Warrior. Which also comes in at under $100. And the Iridium family are pretty nice knives.

https://www.bladehq.com/item--Kershaw-Iridium-Dessert-Warrio...


Sensor Watch.

Uniqlo Ultra Light Down Jacket

Dual-end pliers, like this: https://www.walmart.com/ip/Performance-Tool-W1105-Side-Locki...

There used to be a beefier version that was just perfect; despite over two decades of abuse (dropping off ladders onto sidewalks, letting children play with them...) my first pair is still going strong.

Now you can only buy slimmer knock-offs, but they're still great. Needle nose, std pliers, hex pliers, and wire strippers in a single, rugged tool.


Bidet

Weighted blanket

Shoehorn


Microsoft Modern Webcam - $50 and the image quality is great.

3M WR209 Wrist rest - $20

Logitech M310 Mouse - $20


A nice tea kettle where the temperature is adjustable.

What's it for? It's always better to boil water for tea for hygienical purposes, no?

I'm sure it depends where one lives, but if your drinking water is safe there's no real reason to boil the water except for proper steeping.

I definitely use boiling water with my bagged breakfast tea, but boiling is too hot for white and green tea (especially fancier teas), and boiling water "scorches" the "delicate flavors" (using quotes since I'm sure there are better / nicer words than those), so you want to steep at 80C or lower depending on the tea, the quantity the vessel, and the process.


I found that 200 degrees F makes my tea taste better than full on boiling.

Guessing the hygenics depend on your local water supply, but some varieties of tea (and coffee actually) want to be brewed at below-boiling

You can still boil it and just wait a couple of minutes and use a food thermometer, no?

Yes, it's just really nice to be able to push a button and have it hold at the right temperature; sort of like how boiling water on the stove or in the microwave and using an electric kettle are functionally equivalent but the kettle is way more convenient.

Some teas steep at less than boiling temperature. And I imagine the tea itself may have more risk of microbes depending on how it is stored, and that the temperature drops way below boiling almost immediately upon pouring out.

I wonder if any studies have been done on this....


Some teas(white and green particularly) are better brewed well under boiling, but even those lower temps kill 99.9...% of pathogens in a few seconds(vs a fraction of a second at full boiling)

a good mission burrito is like $10 and makes my life better

$100 on sushi and I’m still hungry. $10 on a burrito and I’m full for 24 hours

Yeah because it's the size of a small child

lmao this was also going to be my answer

fucking condoms

Are there any other kind?

Well there are USB condoms which cut the data lines...
