Works great.I use this watch mainly when I workout and go for running. i generally run along with my friends and the number of steps this watch shows is very less compared to number of steps my friends watch shows. I validated it against multiple different watches and this one definitely shows less number of steps. the other features work but I havent validated how accurate they are. charging is great. once fully charged, it works for 4-5 days. Sync with the app is not great. I have little older version phone and I was not able to sync this watch to the app.This really is a nice watch. It's comfortable, casually waterproof (you can wear it in the shower and to wash your hands), and helps you monitor life stats like blood pressure (BP), steps, sleep, heart rate, and body temperature. It was a bit frustrating to set-up because even when choosing to measure everything via the Imperial method, it kept measuring in Metric, the weather widget is off and reads 69F when it's 78F, there is not a quick method to turn off instead of letting the screen/watch face time-out, and also you need to open the corresponding app on your phone at least once a day or the watch will disconnect from your phone and revert back to metric which is a massive pain and super annoying. Also, even tho I fully charged the battery, it starts as 45% full even after 2 hours of charging. So, if you aren't super reliant on accuracy, and don't mind reconnecting your watch to your phone every day, then you may want this watch.This tracking didn't have the same numbers as my other one for the same routes. I am not sure how it is calculating things differently but it shows less distance than my maps app and my prior fit watch.Other functions seem to work well. Since tracking my distance is my main reason for having this, I didn't keep it.This watch is comfortable to wear and looks high quality. The battery life is great, you can probably go for days without charging. As a fitness watch works great, even tracks your body temp and heart rate. The downside is that the app used (Runmefit) is not as user friendly as I would've liked. You can only set goals in kilometers and only in whole numbers, 1, 2, 3, etc... Some of the links are not in English as shown in one of the pictures. And It did not receive any texts or messages even though I repeatedly connected it via Bluetooth to my phone.This is a great smart watch for tracking fitness. It doesn’t have all the bells and whistles of the fancy watches but doesn’t cost a ton either.I needed a new smartwatch and this one is great! It’s easy to setup and I haven’t had any issues with it so far. It does everything I need it to.
