    This 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!

    This 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.

    This 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!

    I ordered excellent condition, just a few scratches on the edge of the build, but it's covered by the case.Perfect screen no scratches. Great refurbishing job, system works perfectly after having this for 2 weeks.

    Great 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!!

    Very happy with my s23 ultra refurbished purchase in excellent condition. No blemishes or scratches (large or micro) on the screen or body. Swapping my physical SIM card was smooth and the phone was up and working like normal within an hour of getting it. Quick delivery; very satisfied, will absolutely buy from Back market and this supplier again

Here’s what you help prevent on average by choosing a reborn smartphone over a brand new one.

171.1 lbs of CO2e

That's like driving an SUV from NYC to Chicago.

6.3 oz of e-waste

That’s around the weight of a baseball.

537.1 lbs of raw materials

That's like 20 dogs digging in your yard for a week.
