Review: Excellent for the price - I can't believe I was able to get a decent Samsung smart watch for so cheap, refurbished or not. I actually really like this. My previous smart watch was a Samsung, so I knew basic stuff about how to/what to. The watch did come with a quick start guide and a charger, both very nice to have. It has all the same bells and whistles I was used to, plus more. I actually used the flashlight feature last night while my tiny was sleeping so I could move around without turning a light on, and that worked great. The battery isn't too bad for my purposes. I got 2 days out of it, but I tracked steps and sleep only. I did blood oxygen, and that depleted my battery pretty quick, but I just wanted to see what it was like. Neat feature, but not one I need. Anyway, it's on par with what my non-refurbished old watch used to get, so I'm very happy about that. The battery was dead when it arrived, but I got it charging and used my phone to do most of my set-up while it juiced. The other nice thing was a lot of my stuff transferred from my old watch to the new, so I didn't have to add back my alarms and stuff. That was swell. I also like that the watch can do sound alarms, and they're not super annoying or obtrusive. All-in-all, good watch. Happy I took a chance on the refurbished. And the size is just perfect for me, too. I did manage to scratch it already (I just got it this past weekish), but I have a toddler and I'm a klutz, so that's probably my doing anyway. I would like to suggest NEVER taking it swimming, or even in the shower, even though there's tracking for swimming and a "water lock". That's how I killed my old watch. It had/was the same that way, and now I'm just super distrustful of any watch that claims you can go swimming with it.
Review: Still ticking - I've had this for a year and it's still going. It paired well with my Samsung Flip 5. All the features worked and is easy to use. I was able to charge it with my Active 2 charger with no problem. The quality of the watch was perfect. The only thing is I noticed that it requires charging quicker. A full charge last about 13 hours

### ⭐⭐⭐⭐ Really pleased with purchase
*by A***R on July 5, 2025*

So far-Very happy. Watch was in like new condition. Did have issue charging it the first time. The watch kept saying overheating charging stopped. However I was doing updates and system setup simultaneously. It did charge normally overnight. I was unsure if I wanted a galaxy watch and was toying with the idea of joining the fruit phone people because I like their watch. I didnt want to spend ove $100 on a watch I was not sure I'd like. I am glad I came back to my senses. Love this watch
