The watch is light and comfortable to wear. The battery is charged by a USB power supply and lasts for about 7-8 days after a full charge. What I like most is that the clock records how much sleep I've slept each day - how many hours I've been in deep sleep versus light sleep. Blood pressure is also displayed in the app. Pulse is also measured, which is displayed directly on the watch. As well as my daily steps and the kilometers traveled. Every day I set myself a goal of miles that I will walk to stay in shape. What I also like is that you can change the brightness of the clock in the app. At night, I set a low brightness level. During the day, on the other hand, I set the brightness level to the highest where you can still see everything just fine despite the sun shining. The watch even has a camera function. One click on the watch face and a photo is taken by the cell phone. I find the notification handy, so messages and WhatsApp are displayed directly on the watch. So you don't always have to take your phone out of your pocket - perfect! My conclusion: the watch offers everything a fitness watch should have at its low price. Compared to more expensive products, this watch can definitely keep up.
