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.

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.

I have had my refurbished phone for 2 weeks now and I love it! I had my previous phone for 6 years and it was slow and out of date. Constantly glitching out. This phone is much faster and came in excellent condition. Only thing is it gets hot fast when using an app to do video calls. Otherwise perfect. Customer service was awesome as well. I am happy with my overall service and would purchase through Back Market again.

The phone was delivered in mint condition - no detectable flaws. The battery easily lasts a couple of days the way I use the phone. This was my first experience with Back Market and, to be honest, I was a little uneasy buying a refurbished phone. BUT< I would not hesitate to do it again.

Product was in brand new condition. Great communication from the moment I ordered. Any questions or concerns were answered promptly by BackMarket AND the refurbisher!! Delivery was delayed a couple days because of a busier than normal weekend for the provider but that was very well communicated to me. Definitely will use them again.

My refurbished phone arrived and apparently the "fully unlocked" phone I ordered is not fully unlocked. Xfinity cannot start my service because they are showing the phone needs to be unlocked by the previous carrier. My old phone has half the screen blank so I do not have 3-5 days to wait AGAIN to get a new phone or get this one fixed. My main frustration is that back market is not allowing me to contact ANY support to get help with this. The only options I get are to send my phone back or get a refund. If I can get on the phone with the seller they can get this phone unlocked. This is a disaster.

The refurbished Samsung S20 I purchased is great! It arrived in 2 days which was 2 days earlier than promised. I am extremely pleased with this phone and the purchase process.
