I purchased an Amazfit Stratos around 6 months ago. This thing is better than any other smart watch I have owned (Pebble, Moto360, Apple Watch). Always on screen. Multiple days worth of battery. Best workout tracking I have had on a watch. And it does all the notification and smart watch type things I expect. I am not certain why Apple, Samsung, et al haven't figured these things out yet, but other companies have and it is great. Oh let's not forget this only cost me $150.
