Review on 💪 Revolutionize Your Fitness with the Smart Fitbit Flex Bracelet by Jongkol Amphaiphit ᠌

I have the opportunity to compare with Jawbone UP24. There, the set of functions is, of course, much richer, but UP has one fatal flaw: a breakdown of the "strap" is a breakdown of the entire device, and this happens ~ in a year - a year and a half. Got pros: Replaceable bracelet, counts steps accurately enough, does not count steps when you drive a car. Measures sleep well. Got cons: Poor feature set: 1) Does not have a smart alarm clock that would wake up depending on the phase of sleep with the required time lead. 2) It does not measure sleep phases at all, only how many times you woke up during the night. 3) Does not vibrate when there is an incoming call or alert. To make matters worse, the battery only lasts 5 days.
