Yocuby Sport Smartwatch for Android iOS Phone, IP68 Waterproof Fitness Tracker Watch with HR Monitor, Step Counter, Calorie Counter Bluetooth Activity Tracker Smart Watch for Men

Watch looks great.I have not checked it for accuracy as far as BP, heart rate, O2 levels or step counter, but I assume it is correct.This could be a great watch, but it just doesn't stay connected to your phone so you almost never receive notifications. If they fixed that issue, this would be a top notch watch for the money.

The watch worked okay for every day use but there are a few flaws.1st, no matter what you do, the watch will NOT stay synced to the app you need to download on your phone. I was having to re-sync it every day.2nd, it is not as water resistant as it says it is. It says IP68 but just by seimming there were leaks. And any mud at all and the watch is done for.3rd, the app updated automatically on my phone and now the watch is an "illegal device" and can no longer sync. Rendering the watch useless.Its good if you are on a VERY limited budget but otherwise id say pass on it and get something better.
