    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.

    the phone itself came in great condition and everything seems to work fine except for one thing. I'm not sure if it's anything to do with the age of the phone and the fact that it's refurbished or if it's just a problem with the model, but the antenna seems to be worse than my old Galaxy S10+. Places I used to have fine signal barely give me anything at all and I'm lucky if I can receive texts anywhere. Otherwise a great phone delivered on time. I always recommend Back Market

    This is my 3rd phone from grandcity telecom and I just want to thank them for having such prestige condition phones. Literally not one cuff or scratch on this phone. I highly recommend them if you get them as a refurbisher before purchasing.

    Every experience with Back Market is intuitive, painless, professional, and what we all come for, an AMAZING value! I've never had an issue with this company. I've bought refurbished, renewed, and new inventory from them. I've handled returns and exchanges. I have traded in product. I've utilized customer support and every interaction with them has been exactly what they say they offer and more. Couldn't say enough good about this company, the value they offer, and overall just what a pleasure it is to give them my business. They earned it and I'm a loyal customer.

    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.

That’s around the weight of a baseball.
