I am writing this review 9 months after the purchase. To begin with I loved the product, it actually does what is supposed to do. I happened to use it along with an Apple Watch, and very often I compared my heart rate and steps in both devices and they were pretty close. The app is pretty good and information.
My problem has to do with the quality of the product itself:
- 6 months after use the band developed of bulge in the front around the display area, which made it look like there was some water or air. I searched online and apparently and read about several people reporting the same kind of problem.
- About a month ago, it ran out of battery and when I plugged it to recharge, it flashed like the display like crazy and never turned it on again.
