a few weeks ago I bought a Galaxy watch5 refurbished from back market, I got it in the “good” condition for $65 which is a pretty good deal,
there are some scuffs underneath the watch where it charges, but aside from that the screen is scratch free and looks just like new while I’m wearing it.
the battery life is pretty good, if I have AOD on and mainly use it for simple tasks like checking notifications, it will get me through the day with about 55% remaining, and about 35-40% under heavy use.
mine is running OneUI watch 8, which is currently the newest os available for the watch, and it is kind of slow and choppy when navigating through the UI, but it’s still not too bad.
i am planning on keeping this watch for about 3 years assuming the battery stays in good health. but it will only get another year of software support.
overall the watch has been. good purchase and I’ve been happy about it, especially because I bought it for about $30 less than a simple Fitbit tracker, and this watch runs full Android.
