Review on Black HUAWEI Watch GT 2 Pro Smartwatch with 1.39-Inch AMOLED Touchscreen, GPS, Heart Rate Tracker, Waterproof, Bluetooth Calls, and 14-Day Battery Life for Android; Blood Oxygen Monitor Included by Guanyin Lin ᠌

Fantastic wristband that combines the look of a watch with the functionality of a fitness tracker. They can stay alive for around 10 days if their vital signs (heart rate, oxygen levels, stress levels, etc.) are constantly monitored; for about a week if they train (two to four times a week for one to and a half hours); and for about five days if they train using GPS. In fact, you forget that they require charging until it is too late. Even after over 2 years of daily use, the glass remains scratch-free, while the metal has only a few minor dings and dents if you really check for them. I put them through the ringer (sea, river, pool, shower, bath, fire, and copper pipes) and they came out on top every time.
