Pleasantly surprised! I recently bought from this site and I am pleased with my purchase. I ordered a Samsung galaxy s21 5g in excellent condition and it was exactly what I hoped it would be. It arrived with no scratches works perfectly like a brand new phone I can’t tell it’s been refurbished at all. The best part about it all was the price! I will no longer buy from any other website besides back market. I highly recommend ordering from here.

I am extremely happy with my Samsung Galaxy S21. I got a good price on an excellent refurbished phone. It came in the original packaging from Samsung. I could not find any scratches or any indication that it was an used phone. It was easy to activate with Verizon and has worked flawless for me.

I was very satisfied with my purchase from Back Market and the particular vendor that refurbished the device. I bought a "Fair" condition and I was pleasantly surprised with what I got! The only small blemish I see is a 1/3 inch scratch on the screen that looks like an eye lash fell on it. Other than that I am so happy to have a Samsung galaxy phone again!

Order came a day early and in excellent condition. Had it had the factory box you would have thought this was a brand new phone. Battery seems to drop quick but according to diagnostics it's in good working order at 4,000mah so maybe it's just the strain of setting up like I had my old phone. I rand diagnostic both on the phone and backmarket and everything was good to go and I'm happy that i saved a lot of money and feel like I splurged on a new phone. The seller cellfee is great. I bought a smart watch off them like 2 years ago on another marketplace and I still use it daily which is why I'm OK checking out refurbished items now. Thanks for a great deal and smooth transaction experience. I will always check here first for my electronic needs before buying new.

The phone is nice and in good shape and I loved the price. It is not recognizing a sim card though. I went to my carrier and we tried multiple cards and lots of troubleshooting. I am going to trade it in for a new S23. If not, I would have checked into sending it back for a different refurbished one.

I love Black market, great prices, great refurbished phones. The Galaxy s21 I purchased is a nice phone, I believe I bought it listed as fair condition but the phone is in great condition. Way to go black market !!

Reviewed in the United States on December 29, 2022

The phone works perfectly fine, the screen has no damage or dead pixels, the camera is great and the battery seems to be in really good condition. The only detail I noticed were a few minor scratches on the paint, since I use a case It does not bother me but it might be a deal breaker for others. To be honest I was worried about buying refurbished but I was pleasantly surprised that things went smoothly.
