Verified purchaseI recently purchased a Samsung Galaxy S23 Ultra from Back Market and wanted to share my experience. As someone looking for a high-end smartphone without paying full retail price, Back Market offered exactly what I needed. The ordering process was straightforward and user-friendly. The product listings clearly showed the condition of the device, included accessories, and warranty information. I appreciated the detailed grading system that helped me understand exactly what to expect from my "refurbished" purchase. My Samsung Galaxy S23 Ultra arrived well-packaged and in the condition described on the website. The phone functions perfectly - the powerful Snapdragon processor handles everything I throw at it, and the camera system (especially that 200MP main sensor) takes incredible photos. Battery life has been excellent, and the screen is flawless with no signs of previous use. What really stands out about Back Market is their commitment to sustainable tech. Knowing my purchase extended the life of a premium device while reducing electronic waste made me feel good about my decision. Their customer service was responsive when I had a question about delivery timing. The 12-month ...

Verified purchaseI can't justify spending over a thousand pound on a phone so I decided to buy a refurbished galaxy s23 ultra, I paid extra for an immaculate screen but left the body as gently used. In all it cost me £415 and I must say the phone looks as if it's hardly ever been used, the screen is perfect and the body is also in perfect condition,not to mention the fast delivery. I will be ordering 1 again for the wife for her birthday.

Verified purchaseI ordered a 'good' condition Samsung S23 ultra Sunday afternoon. Paid a little for faster despatch and received Tuesday morning. I am so pleased. Only marks I can see to suggest it is a refurbishment is a little scratch near the charging port. Thank you so much 👌

Verified purchaseThis is the first time buying a refurbished phone so I was a little worried. I brought a phone in 'good' condition and have to say I'm so impressed. It's in near perfect condition and is working as if it was brand new. I paid extra for the faster delivery and it was delivered the next day. Will definitely be using this company again.

Verified purchaseExactly as described at a fair price. Perfect for my teen son who wanted a decent phone model but wasn’t fussy about new/refurbished. Very pleased with the product and service and would buy from Backmarket again.

Verified purchaseFirst time, taking a 'punt' at a refurbished phone purchase & was not disappointed. Outstanding, fast (less than 48 hours) service from initial order to receiving my S23 Ultra (advertised as in excellent condition) & of which was in 'mint condition' at a price that is a fraction of the current retail price. No nonsense customer service between both Back Market & delivery company was fantastic; notified / kept informed of said delivery every step of the way. I highly recommend (it's a no brainer), if you are hesitant of a refurb purchase - this is one customer that will defo be opting for the refurbished purchase option in the future (Back Market is the place to shop!)

Verified purchaseI ordered a good grade phone so expected it to have some blemishes on the back and sides which it did. As the phone will always be in a case this is not an issue. However the good description states that the screen should be flawless but unfortunately there are a couple of feint scratches. Once I'd applied a screen protector these can't be seen so not serious enough to warrant returning the phone. So, overall I'm very happy with my refurbished S23 Ultra which was significantly less than half the price of buying one new. The order process is straightforward and phone was delivered on time so would definitely recommend Back Market for buying quality refurbished tech.

Here’s what you help prevent on average by choosing a reborn smartphone over a brand new one.
That’s like driving an old banger from London to Edinburgh and back.
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
