These guys are criminals. They have advertised their T-Watches as super tough, water proof, and with features they just don’t have. Eg. I was specifically looking for a device to measure heart rate. Their site said it did it all. The watches have arrived and it turns out they have lied about the features. I have been scammed out of my money through deception. DO NOT BUY FROM THIS COMPANY BTW these super tough watches were a joke. We bought 5 and opened 2. One had a faulty display and would only partially show the seconds counter, the other got wet and fogged up so we can’t actually tell if it is Working anymore.
