    The watch is good. I bought it for the second time. It has a long life and beautiful style. It would be better if it had NFC. I'm looking forward to updating it and will continue to buy it.

    My colleague and her husband bought one alone. The one they wanted to buy from Huawei was smaller, but the parameters were almost the same. They directly adjusted this cheap one. It was OK to take it with them. They could measure the heart rate and the number of steps. At the end of the day, it was just enough to see the time

    After several days of use, the appearance is pretty good, but not too heavy. I feel that the battery life is fairly good, and the main functions are very accurate. The disadvantage is that the bound APP cannot be hidden in the background of the phone. Often, the classification of the sports mode is closed carelessly. There are too few dial selections, and the screen sensitivity is not very high, but it is enough
