    • Pretty cool watch
Color: Black
While the battery life leaves something to be desired, the watch is pretty great. The fact that it's refurb doesn't seem to be the cause of the battery drain, it's same for new ones based on what I see on the interwebz. The watch band that was sent didn't fit the watch I received, but the seller did issue me a partial refund so that I could purchase an appropriately sized band. Just an error in shipping, which they did resolve with the refund. Overall a good purchase and the seller was very responsive in correcting the issue with the band. ... show more

    • It's as expected.
Color: Black
This is my first time getting a watch from Samsung. Previously I've used fitbit watches. So, my review. ____ Pros ----- 1. I like the style. Very nice, and it fits well (which is great because I have massive wrists, and normally have to get different bands.) 2. It's very easy to use once set up, and has a lot of customization features. 3. So far, haven't had any issues with the buttons getting stuck, or sticky.(I've only had it for a month so we'll see.) A little hard to clean dust out of the area where the bands connect (I work in a warehouse full of dust. So that's probably just a me problem) _____ Cons ------ 1. It takes a very long time to charge, and tends to die fast if it's not always plugged in. The charger does not always work, especially if it's plugged into an outlet with literally anything else plugged into said outlet. 2. It gets very hot while charging and I have to detach it from the charger one in a while to let it cool down. 3. It says it tracks my walking routes but I have no idea how to access them. I have tried looking it up, but I'm not the greatest with this stuff, wish it was easier to check. 4.the bluetooth can be a bit weird sometimes. It will connect to my earbuds randomly. Hope this helps someone ... show more

    • Asurion BAD protection plans
Color: Black
Watch worked fine till the battery stop charging. If you don't give the right answer, asurion won't honor the protection plan. Walmart use to do the same thing. I might have to hire a lawyer and sue asurion or amazon. I paid for a 3 yr protection plan. I just want them to fix this one or swap out.

    • Great Fitness watch
Color: Black
I ordered the Galaxy fitness watch 4 renewed...it cost less than half the price of new, I was a little skeptical about not purchasing a new one but when I received it was absolutely perfect both cosmetically and functionally. It still had the factory protective stickers on the band as well as the charger, it's a great item it does every thing I need it to do and more! Go for it you won't be disappointed. ... show more

Review Image by Rachel Black
So first things first I am a smartwatch virgin until now! My product arrived exactly as described, well packaged, and ready to go. It hooked up seamlessly (with the help of my 14yo daughter 🤣) to my Motorola G 5G with no problems at all. All of the Samsung health functions seem to work pretty flawlessly, the only thing I can't use is the ECG but I knew that going in since I have a non Samsung phone. The wrist band that came with it is comfortable enough to wear to bed! I read a ton of reviews about battery life and I must admit the 1st day I wore it I thought the reviews were correct, but I love gadgets and I probably fiddled with it more than most and I had the brightness all of the way up and by 10am it was at 17%. I adjusted the notifications, and a few settings including when the screen turns on and brightness. I easily get at least 2 days on 1 charge. All in all for the price I am so impressed and I would definitely recommend and buy from this seller again. If anything changes I will edit this review. Hope this is helpful for everyone looking to get a smart watch. ... show more

    • Samsung Renewed Watch 1.5 stars
Color: Black
Failed to excite me. Have an Apple Watch and when comparing the performance found that the Samsung failed which I was surprised by . Could not adjust the screen movements to allow for no touch required which if you are busy doing anything is a big deal to have to find the sweet spot to tap. Battery faded so quickly once connected to my phone it was not possible to get a full day of use. The watch alerted you each time the battery dropped 5% once it reached 45% and it dropped so quickly it was painful. Maybe a better bet to get a later version with a new battery, but new battery should have part of the renewal for this item prior to sale. Very disappointed! ... show more

    • Incredible product, blown about at the quality for this price.
Color: Black
This watch has been a revelation. I didn't expect much and thought there was a 50% chance I'd be returning it. Wow, was I wrong. It's so fast, helps me stay off my phone and is super fashionable! I love the way it looks, the fitness features, media controls, etc. The battery lasts ~ two days with always-on display turned on but all the data connections other than bluetooth turned off. It also looked absolutely brand new, even as an Amazon renewed product. Very impressed, one of the best purchases I've ever made. ... show more
