Verified purchaseThis was my first purchase from Back Market and I've got to say, I am beyond impressed and pleased with my phone! I was so hesitant and nervous spending so much money on a refurbished phone, and on top of that, using this website because I had never heard of it... but my phone came in almost perfect condition and has been so awesome! I got the Samsung Galaxy S23 Ultra at "good" condition, and 3 weeks into it, this has been the best phone I've ever owned! The battery lasts all day, the screen and camera are so clear, and it's been fast and efficient with everything so far. I couldn't be happier with this phone so far! I am so glad I stumbled across Back Market!

Verified purchaseThis was my first time buying a refurbished phone & the first time I've ever spent so much money online & in general at once. I was nervous about it after realizing it was being delivered thru FedEx. UGH!!! I'm happy to say that my phone is PERFECTLY FLAWLESS (lol)! I ABSOLUTELY LOVE my Galaxy S23 Ultra got the lavender color i wanted with the 512 GB. I didn't know that the color of it would make a price difference, ya learn something new everyday lol. I'm referring BM to everyone i know. I've been saving my coins for a couple years & FINALLY cashed them in so I could purchase this phone. I could've gotten the Galaxy S24 Ultra but that would've left me broke & I didn't wanna be broke lol. Besides I needed to buy screen protector and a case so that's exactly what I did. BM ya'll are the BEST & thank you for existing I'm a customer for life.

Verified purchaseThis is my fourth purchase with BackMarket, and like always, they've delivered me a wonderful refurbished piece of tech! I've been wanting a new phone with space and the S23 Ultra was calling me, plus, the color is hard to say no to. I used their Trade-In Option as well, they where very communicative and I received my new phone and sent the old in without a hitch!

Verified purchaseGreat experience with Back Market. Got a refurbished Galaxy 23 ultra and it was perfect. Couldn't face spending so much money on a brand new phone, so this fit the bill. Great price, fast shipping, and great communication. Bonus was the discount code for signing up with Visible. Saving a ton of money compared to Verizon. Will definitely use them again!!

Here’s what you help prevent on average by choosing a reborn smartphone over a brand new one.
That's like driving an SUV from NYC to Chicago.
That’s around the weight of a baseball.
That's like 20 dogs digging in your yard for a week.
That's like running a faucet for 3 days
