Very light, excellent battery life

I love the TRex Pro. It's amazing: So light, the battery lasts days without recharge. All the right functionality with focus on health. Buy it and you will love it.

Almost perfect, only flaw I noticed Is when my batt level gets In the 30s workout modes with GPS do not work well, plus heart rate reads wrong.

This watch is a wonder to behold. It is comfortable, versatile, accurate, durable and easy to operate. The battery power is also quite impressive. The Zepp app is easy to read and manage. And on top of all that, it costs less than $200. Terrific bargain!

So I have owned all 6 apple watches and I also own the Samsung Galaxy watch, and the Garmin Instinct Military. I will say outside of not being able to take calls or answer text on it and yes I am sure the other have better heart and Sp02 sensors,.. But in the end best smart watch you can but dollar for dollar.
