    I was a little nervous getting a refurbished item but I was really surprised on the quality of the watch. It lasts me about 12 hours and alittle more. Definitely a returning customer!

    Initially, I was about to send the watch back. The battery was literally dying in front of me. After doing some research, I determined that I did not need all of the apps running in the background. My battery now lasts all day! The purchase was quick and easy. The delivery was fast and I am now enjoying my watch. Thank you!

    Looks just like shown. Works great. As always, completely happy with all the processes involved with purchasing with Back Market. Love re-using technology and putting my money into places that support the environment.

    Minor scratches on the screen and all around but it isn’t a problem, the button on the side to power it on seems a little smashed. Overall the watch is really nice, the charger that came with it was open but there was no damage.

    My wife loves the watch. It has many features that she[s using, and some features we didn't even know existed on a smartwatch. Also, I got her an Apple Watch specifically because she has an iPhone and an iPad. These work together extremely well.
