Samsung Galaxy S23 Ultra review: The Refurb Buyer’s Dream? | Back Market

The Samsung S23 Ultra might be a two-year-old device, but we wouldn’t be so quick to write it off just yet. This phone outclasses and outperforms many of the phones available on the market. In this review, we explain how.

    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!

    ⭐️⭐️⭐️⭐️⭐️ 5/5 – Great Refurbished Deal! I recently purchased a refurbished Samsung Galaxy S23 Ultra and honestly, I’m impressed with both the product and the service. The phone arrived extremely fast—just a couple of days after I placed the order, which was a pleasant surprise. As for the phone itself, it looks and feels like new. No scratches, dents, or signs of previous use. Everything works perfectly—from the screen responsiveness and camera quality to the battery life and performance. The S Pen was included and functions flawlessly too

    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!

    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.

    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

    This is the third item I have purchased from back market. I truly don't foresee ever buying electronics brand new again. The phone came in record time, in stellar condition. You would truly never know it was refurbished. It works great, I have had zero problems with anything I've purchased from back market and the Galaxy s23 Ultra was no different.
