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: My first smartwatch... will it be any good? - While reading the reviews here, I honestly was slightly discouraged. But in researching a possible smartwatch I purposely looked this model up and seeing that it takes some tinkering to get the battery life to last, I decided that I'd at least try this one renewed in excellent condition and just see if it would be what I was looking for. It arrived about a day and a half after I ordered it and was in surprisingly as good as new condition. I did a hard reset to wipe anything on it as soon as I charged it fully. In doing that I had to update the watch to current wear OS and UI updates. Then just loaded the apps that I believed would be the most useful for me. I don't need the watch to monitor my health in 5 different ways constantly going on in the background...so I only manually use those features when I need them. Since I have only had the watch just a few hours, I couldn't give a full review just yet. But from the optimizations I put on the watch, I feel optimistic that it will perform fantastically...but will report back and give a final review update after a couple of weeks. But initially I'm impressed. So after a full week of use it seems to be a really good purchase. If you're on the fence about buying a smartwatch, give the excellent condition refurbished one a try. Now don't expect to be able to have a bunch of complications and everything turned on 24-7. You'll drain the battery down to nothing in 4 hours if you do. Just turn on exactly what you need. If you really turn down the settings, you'll get a couple of days before a recharge. With my use, I recharge it every night for an hour or so to top it off for the next day's use. I did use it once overnight to monitor my sleep and it did just fine. Usually when completely drained it takes about an hour and a half to fully charge.

### ⭐ Badly
*by V***N on May 13, 2026*

I am very disappointed with this purchase. The watch looks fine, but the battery dies in only about 4 hours with normal use. Even for a renewed device, this is unacceptable. I would like a refund because the product does not meet expectations.
