Spotless - Definitely a difference between a 3 categories fair-great or whatever it is. Pay the extra for the best available. It is worth it.

Galaxy active 2 - Very good watch n was in very good condition just need more memory

JeeCaOct 29, 2024 · Verified purchase ★☆☆☆☆

Not good for the long run - This is the 4th Samsung watch I’ve purchased where I have run into battery issues after a short period of time. The last one I tried to purchase a refurbished one thinking maybe because it’s already been repaired, I wouldn’t run into the battery issue with a brand new one again. No, that was not the case. Just ended up running into this issue once again but sooner than the brand new ones. Just when I had faith in Samsung, the same issue happens with all my Samsung watches that I’ve purchased from BestBuy.

Best watch ever - Still used and love it, water proof and durable...
