3 stars: It cool but only the sleep tracker isn't working
4 stars: I've had the watch for about a month and my only qualm is that it won't sync to Google Fit. If you're having notification issues - just manually add the app you want to push notifications for. When the data isn't accurate, just pull down in the app to sync. i feel most of the complaints are from users who haven't taken those steps. However, I haven't experienced the watch disconnect, and hopefully I don't! Good watch for the price.
3 stars: Kudos to the developers for making something like this. However, there are a few faults. One of them is that when you put on your Bluetooth and connect to the watch, after about 5mins, it automatically disconnects. So the watch can only inform you about a message or call within that 5mins. I also think that a lot can be done to improve the device.
4 stars: Update: after removing the app and reinstalling the app it started working fine again, so I give it four stars, there are some minor issues but it works fine and so is the watch. (It worked fine for one year, but after update the app crashes every time.)
3 stars: It for the most part does what it's supposed to. I wish It would update more frequently, like real time numbers. And I can't get mine to sync with Google Fitness. But it's the only app that syncs to my super cheap fit-watch device that I ordered online for $15, but you get what you pay for
