Has a long battery life, useful tools and is durable. Touch screen doesnt work in the water to well, and bluetooth connection distance is a litte short is my only complaint. 140 was a good price for what its worth
I definitely would not pay 300$ for this watch, it does everything you need it to do. It tracks your steps, heart rate, blood oxygen levels, calorie burning and all sorts of different activities. Plus you can swim with it but make sure you clean it after your in salt or saline/chlorine based waters. It even tracks your sleep patterns!
I really want it to be good but it seems to be a bit lacking. The build seems a little too light weight. But over all I like it. Processing system seems a bit sluggish.
