GT Upgrade Sport SmartWatch

Very good product

Very fast shipping, just try it.

Very cool watch

A nice envelope, a big onion for my friends will drop when they see it, a nice compass, pressure measurement at any time

Good product for such cost. Quickly delivered, was well packed. Everything works without brakes. I would like more interchangeable screens or loading my own (full screen customization up to the selection of arrows and font).
