    Once again, Back Market has delivered a "like new" refurbished phone. The phone works flawless for now, and the delivery process was seamless. I'm so grateful for this company. Hopefully, they will never cease to exist.

    Been very happy with this first purchase on back market. Arrived about 3 days earlier than the estimated delivery which was a nice surprise. Been using this refurbished phone (excellent condition) that released back in 2020 for about 2 weeks now and wow it's been in working fantastically. The battery works like it's new. All the buttons work as does the fingerprint scanner, no issues with the cameras. I have yet to find any issues and the 120hz motion smoothness is worth the sacrifice in resolution to keep it more in line with most current flagship phones. My only complaint is that there are minor superficial scratches on the screen from obvious prior use but are only noticeable when screen is off and actively looked for.

    I feel like i found a lifehack to finding quality electronics at a fair market price. The peace of mind knowing the device was refurbished by qualified provider and met BM quality standards provides peace of mind in purchasing any device. The device shipped and was surprised it was not brand new. Absolutely a great offer using Back Market. Thank you!

    It was all i hoped it would be. Looked like new. Every function worked as it should.Be sure and put a protective case on it as soon as you receive it. Learned the hard that you don't put phone in your back pocket and set down. Broke the back glass day one...It's still an awesom phone. I will probably buy my next phone from Back Market.

    Small error in the initial order however they worked Fast, allowing me to get my phone only a few days late.As opposed to months period as for the phone itself it arrived exactly as described period I was totally aware that the phone I was getting would not get security updates after this year, But after a lot of research I discovered this phone would carry me until I had enough to upgrade to the next level. The phone works fantastic. I changed over from an iphone mini to the s twenty ultra. I have To say it has a much better camera than my iPhone. And I've been really happy so far with the customization abilit and ease of use. I highly recommend back market for your tech needs. The cost and the quality are just too good to pass up. I've never had a bad product and this is my fifth product ive bought from them.
