    I ordered an S23 ultra in good condition, had a tiny scuff mark on the top of the case, not realy noticeable at all. The battery life is excellent and so far seems as good as new. The screen has no marks or scratches,the cameras all excellent and pristine. Highly recommend buying a refurbished phone and would probably use back market again in the future.

    I bought a refurbished s23 ultra in good, and the phone is perfect, I really couldn't see any marks on it, but that wasn't an issue as I always use a case. But when the time comes I will buy from back market again.

    Fantastic experience with BackMarket. First time I'd bought a refurbished phone and it was a great success. The phone is in exceptional condition, looks the part and functions at 100%. I was concerned about the battery life but the phone exceeded expectations and for a fraction of the price. The red colour makes it unique and very glad to try out BackMarket and will definitely buy more of my electrical needs/goods through this site! Would highly recommend!

    Am very happy indeed with my S23 ultra. Looks and feels like new. No scratches or marks. Had for a few weeks now, and all appears to be working perfectly 👌 Was worried about buying my first refurbished phone, but the 30 day returns policy swayed it for me. Will return to Backmarket when I'm ready to buy again.

    Fast and hassle free delivery, phone arrived well packaged and in excellent condition. Great communication from the Back Market team, already recommended to family and friends to purchase refurbished tech in future and buy from Back Market, you'd be mad not to!

    what can I say, was very apprehensive as this was my first experience of buying a refurbished phone but on arrival of my S23 ultra I was amazed, I spent 30 minutes looking at it like a lovestruck teenager and as a 66 year old quality executive that's quite a thing, my new phone had NO visible defects whatsoever and the battery was spot on, all functions work well and the camera WOW, can't wait to get this bad boy on vacation and start taking some magnificent photos. ☆☆☆☆☆ Service ☆☆☆☆☆ Product I will be back next for a new phone for the good lady wife.

    Phone works perfectly, and for almost half what they sell for new. I ordered a Galaxy S23 Ultra in fair condition, what I received exceeded my expectations. There were minor scratches on the screen that were only noticeable when a bright light was shone on them. There were also one or two scratches that were more significant, but not noticeable when the screen was on and these disappeared completely with the application of a decent Dome Glass screen protector. The back of the case was in excellent condition, but there were a few scratches around the charge port, and some small dents on the camera surrounds, no scratches on the actual lens. With a case and some camera lens protectors on its not noticeable at all. Only problem was the charge cable wasn't good enough, the phone would complain that it wasn't connected securely, after switching to one from another Samsung phone it worked fine. Overall I'm very pleased with the purchase and would buy from Back Market resellers again.

    I'm a new customer at Back Market. I saw many good reviews and decided to buy my next phone through the website. I chose the very good condition and was quite anxious to wait for my order, the Samsung Galaxy S23 Ultra to arrive. I was relieved when I received it and happy because the phone worked well and just as I expected. I use the phone daily now and haven't got any problems at all. Thank you Back Market for making my phone wish come true

Benefits of buying a refurbished Galaxy S23 Ultra at Back Market

 

At Back Market, customers save up to 50% off compared to the price of new on certified refurbished Galaxy S23 Ultras. The best part is, you don't have to sacrifice performance in order to save money; all refurbished devices on our marketplace have been fully reconditioned, cleaned, inspected and tested to the same standards as a new one. This is the biggest difference between buying a used or second hand Galaxy S23 Ultra compared to a refurbished one.

Buying a reconditioned Galaxy S23 Ultra is also a much friendlier environmental option. Refurbished Samsung mobile phones are often second hand or used ones that have been restored and updated to meet the manufacturer's standards, which means you'll be helping to keep old cell phones out of our landfills, reduce electronic waste, and minimise your carbon footprint.

 

Where is the best place to buy a cheap refurbished Galaxy S23 Ultra?

 

If you're looking for cheap Galaxy S23 Ultra deals, but without the compromise on quality and performance, then Back Market has you covered. With Galaxy S23 Ultra prices up to 50% less than brand new, and a thorough screening process for refurbished sellers to partner with us, you can rest assured that your reconditioned Samsung Galaxy S23 Ultra will perform just like new.

Staying true to our brand, we're also a huge advocate for environmental change. In fact, at the beginning of 2023, we hit a milestone for preventing 1 million tons of carbon emission (CO2e) from entering the atmosphere. You can help contribute to a better circular economy when you shop cheap smartphone deals on our platform.

 

Is it better to buy a reconditioned Galaxy S23 Ultra instead of a used or second hand Galaxy S23 Ultra?

 

Buying a used or second hand Galaxy S23 Ultra with no guarantees that the device has been refurbished, nor a return policy or warranty poses a huge risk. Thankfully, with Back Market, we don't just list certified refurbished sellers, but we also add in a minimum 12-month's warranty, 30-day return policy, and free delivery too - all at no extra cost! If you're looking for a cheap Galaxy S23 Ultra deal in the UK, look no further than Back Market!

 

What to expect when buying a refurbished Galaxy S23 Ultra

 

If you're a first time refurbished buyer, you might not be sure what to expect from your purchase. First, understand that your Galaxy S23 Ultra may have external cosmetic flaws depending on the condition you choose (Back Market offers devices of Fair, Good and Excellent quality). However, whatever the condition, any external blemishes will not affect the performance of your refurbished Galaxy S23 Ultra and you can expect your device to perform as if it were newly opened directly from the Store. You should also be confident that your Galaxy S23 Ultra is backed by a 1-year warranty, meaning in the rare case that any defects arise (outside of accidental damage) within 12 months of your delivery date, then you're entitled to your choice of a repair, replacement or reimbursement.
