Up your game with

Samsung Galaxy Watch3 45mm is rated 3.9 out of 5 by 13.
Rated 1 out of 5 by from Galaxy watch 3 Having just bought it I find it halarious that when the new model just coming out will be exactly the same internally, but with a new operating system that won't be compatible with the old one.

Rated 1 out of 5 by from Poor GPS / Poor Battery Bought this watch to use with My S20 phone, thought it would be great combo. Recently (a few months after purchase) I have had issues with GPS / Strava failing on it, usually recording the first few km of a run/walk then just freezing and not recording anything else. As a fitness tracker that is unacceptable. The battery life of the watch is shocking, I'm lucky to get 2 days out of it, (that's without using the gps/tracking). I would not recommend this watch to anyone.

Rated 5 out of 5 by from First Smartwatch This is my first Smartwatch so don't have anything else to compare to. What I can say is I've loved every minute of it. I wouldn't say it's a necessity but certainly a nice-to-have. I like how it syncs with my phone so well, especially with notifications, and tracks everyday things superbly. Battery life could be improved but still lasts me 2 and a half days.
