Bests & Worsts Reviews from Amazon

I got this watch mostly for its ability to monitor a heart rate and to last on a single charge for up to 45 days (according to the manufacturer). The watch failed in both. Pros: • Beautiful design. Looks like an Apple watch. • Lightweight. Super light and super comfortable. You’ll forget you’re wearing it. • Always on display is a big plus (although the watch faces selection is abysmal and looks like was designed by a 10 year-old in the 80’s). Cons: • Heart rate monitor is more like a roulette game. You get random numbers that most of the time have nothing to do with your actual heart rate. I confirmed it by the manual count and by using a pulse oximeter (see pictures). The difference can be 40-60 BPM! So if you need a reliable HR monitor look somewhere else. • Amazfit promises Bip Lite to last “up to 45 days on a single 2.5-hour charge”. In reality it lasted less than 3 days!!! (see the screenshot). Now I understand that all companies make exaggerated claims re the days the charge lasts and I wouldn’t mind if it was 40 or 30 days. Heck, I’ll even take 20 days! But 3 ????!! Bear in mind that I didn’t use it to monitor any exercises. I also didn’t use it to check texts or incoming calls notifications. Or any notifications, messages, alarms whatsoever. Nothing except monitoring my HR. So 45 days is a total deception. I can’t speak about the pedometer or calories count as I have no other watch to compare the numbers to and also I didn’t really care for it. To sum up: if you want a reliable smart watch this is not it. I wish the company was less deceitful in its advertisement. ***Update*** Yesterday the watch attempted to update its software (btw, you can't block it) and during the attempt it got frozen. I tried to turn it on and off, tried to reinstall the app- nothing helped. Now it's totally useless, can't even show the time. Downgrading to 1 star and sending it back.
