Worst experience ever.
One of the worst decisions I've made is that I bought two Huawei GT3 pro watches for myself and my wife and both of them have problems not turning on anymore. And as for customer service, I would say a real maze in terms of returning and repairing one of the watches it took me about 3-4 months. and they wouldn't accept the return of both watches at the same time you had to apply separately. In short, I would never advise anyone to buy there.
