Had the amazfit pace before so I decided to go for the Trex and Im glad I did. I do alot of hiking and swimming outside of running and this watch suits all my needs. Definitely would recommend.

Inexpensive tech that totally delivers

The headline says it all... What I wanted was a digital watch to accompany my workouts, and the T Rex delivers. Multiple workout tracking, heart rate, steps, calories, and even analyzes my sleep patterns. Paired with the Zepp app, it's everything that I wanted/needed and nothing that I didn't. Built strong with multiple face options. Most satisfied.

After a week, my fiance LOVES this watch. For the money, you can't beat it. It has a few options that my Galaxy watch doesn't. I ordered him the amazfit buds after we saw the quality of the watch. Can't wait to get them!!!

I own the gtr and whas expecting them to be compareable, but the lack of watch faces and not alexa friendly is disappointing

The watch is proving very useful to me because I have a monitoring of sports activities and control of my blood pressure.

It tells time really well

I did a lot of research on this watch and excited about the articles written about it. Worked well for a few months. A year the watch will randomly shut off then on. It has reset its setting multiple times. When it resets you have to go in and change your settings. Lastly the band broke. For a rugged watch I would've expected higher quality stronger band. Better off with a fit bit or Apple Watch

3 to 4 stars

Holds a charge for many days - a good, long endurance. Heart rate measure bounces around a bit, and steps measure seems way low. The flexible, stretchy wristband is the best. On my FitBit Versa three wrist bands wore out in a short time, adding unwelcome expense. The Amazfit gives a much better reading of sleep statistics than the FitBit did, partly, I suspect, from the better fit of the wrist band.

Yes, you can leave your phone at home if you're going to be running. You can start your run from the watch and when you get your phone and open the app, your data from the watch will synchronize with your phone.
