Review on Amazfit T-Rex Pro Smart Watch: GPS, Outdoor Fitness for Men, Military Standard Certified, 100+ Sports Modes | Waterproof 10 ATM | 18 Day Battery | Blood Oxygen, Heart Rate Monitor by Edyta Kot ᠌

Its pros: After using Amazfit bip for two years, I switched to this watch. Pulse is MUCH more accurate than bip. They do not fail when wet, do not work from wet clothes, etc. Cons: If you do sports every day, you have to charge every three days. They charge very quickly, it doesn’t bother you much, but you can’t go on vacation without charging.
