Overall for a sub-$40 watch that offers more then the competition and dare I say the best watch out there I think for below $200. but all watches below $100 lack something.I'm happy.battery life and charge time are good, charge it once a week.App: the app lacks features, change the face, adjust sensitivity, and some others.App Charting: there are no trends and charts.Looks design: looks pretty good. there is NO NEED for 3 buttons on this thing. Unless it does more on other models. but literally no need.Watch menu: menu system is a little confusing. had to watch a 10min video on it. Overall I got the hang of it.Settings Menu: IDK still can't figure it out. and the app lacks these settings.Tracking: NOT a good step tracker, too sensitive.GPS tracking. must use the App in tandem with this. don't see the benefit when I have google fit and others for this.Google Fit: will report Steps, Sleep, and Heart Rate only, for some reason won'tMyFitnessPal: no support yet. but honestly it will grossly increase steps. Soooo, IMO a high estimate that consistently high is better then nothing.Durability: Pretty good so far. no scratches on the face.Wrist Band: a pain to take off, a little 'grabby' its silicon. Prefer cloth Velcro or quick release.Body Scale and integration with similar Tinwoo Products: such as 'FixIndex'. in short; NOPE. even though they have the same programming, background, etc... they don't integrate.Luckily Google Fit consumes this.
