Kospet Tank S1 Smartwatch

This is my third purchase from Kospet and I have yet to be disappointed. This one was a Christmas gift for my wife to replace an Apple Watch. Set up was easy as usual with Kospet watches all functions worked great and the wife is extremely pleased with her new Tank S1 Smartwatch!
