I am EXTREMELY impressed with this watch. This is very similar to an Apple watch, and that's a good thing! I purchased another smart watch from a different brand a few months ago and it was no where near as good as this. This watch does everything I need it to do. The app is very easy to use as well, connecting the watch to my phone took less than a minute. My favorite feature on the app is the Sleep Tracker. The sleep Tracker monitors how long you've been asleep, either in deep sleep or light sleep. Everything seems to work as it should. It tells me when I get text messages, when I get phone calls, without having an annoying chime, just simply vibrates. The battery life is also very good, you definitely won't need to charge this every night, you can go about 3-5 days depending on usage. Best of all, IT'S WATERPROOF!!! I get to wear this in the shower which is awesome, Even when washing my hands, I don't have to take it off all the time. I 10/10 recommend this to anyone who wants a better, more cost effective smart watch.
