If you are looking for a smart watch that has all the basic functions (GPS, health monitoring, fitness, connection to your phone, etc.) but don't want to shell out the high cost of an Apple Watch, then the Tank M3 Ultra from Kospet is worth considering. It has all the basic functions (and many advanced functions as well), high quality build, it's waterproof, easy to pair with your phone and is MUCH less expensive than other similar smart watches. And the battery life is INSANE - like over 3 weeks on a charge insane battery life. In this video we show you how the Tank M3 Ultra works, demonstrate some of the things it can do, and dunk it in water to see how it handles the challenges!
