+2 pts“Go away from T-Rex 3 right now. Amazfit released T-Rex 3 Pro and all the software goes for T-Rex 3 Pro. and metrics of T-Rex 3 (readiness crap and sleeping) are pretty terrible so if you want Amazfit go for T-Rex 3 Pro or Balance 2 or GT 5 Pro but not T-Rex 3.”

What Redditors Say
Best praise vs top criticism for Samsung Galaxy Watch Ultra
Best Praise
+3 pts“Its a nice way of being in contact etc... without having to hold / look at your phone all the time. I have a Galaxy Watch Ultra which is amazing and has its own data and a xiaomi watch pro 2 which is a lot cheaper but has the main features and will update to Wear OS 4. If you want to try a cheap one, look at either unknown cmf watch or one watch 2 r (they give you a lot of free stuff)”
r/Smartwatch
ViewTop Criticism
+4 pts“There areany really accurate smartwatches that measure blood pressure available in the U.S. . None have been approved by the FDA. The closest you can get is the Samsung Galaxy Ultra, but you have to do some serious hacks to import the blood pressure monitor from a European app. I've tried several and the blood press was always off by 20 or 30 points. I checked them using a medical grade blood pressure cuff.”
