I do like the improved sleep tracking which adds REM calculations to the deep and light sleep of earlier models.

For a few months this watch was everything I wanted in a smart watch:-Good battery life-Great health tracking-Solid sleep tracking-Easy to read in daylight-Round

The display is certainly not as sharp as it could be, but overall this watch is a great value at this price point.

I read in some reviews that the way the watch is shaped led to fingers getting scratched as you use the touchscreen/swipe.
