Absolutely dissatisfied! The product came broken and it was not clear how to proceed! first they sent an e-mail informing that they had opened a dispute and then I only found out how the situation was when I opened the Ali Express application, where there was a message there telling me how to proceed and honestly, very difficult to understand the process! I paid a price on a broken product and will have to pay the cost of shipping from Japan to China, that is, the price of the watch! absurd! Last time I buy something a little more expensive here! Very unsatisfied!
please remember that battery works just for one day in normal usage - all measurements are turned off and no sport mode selected. Just notifications from smartphone.battery life is epicly bad or I recieved damaged item. still seller didn't want to cooperate in this case
