This is the second time I've purchased a refurbished phone from back market. My S20+ lasted years, but after I dropped it the usb and sim card slot stopped working, so I decided it was time for an upgrade. The S23 Ultra arrived in perfect condition, not a single mark on it. The battery life is great. It doesn't heat up during intensive use like my old S20 either. The optional insurance is brilliant too, it takes the worry away if anything happens to the phone. I would definitely purchase from Back Market again, and I recommend them to everyone I know looking for a new phone. I do have it in a robust case to protect it from any accidental drops. The second picture shows it next to my old S20+ for size comparison.

Bought this to replace an accidentally smashed Galaxy S20 Ultra for my daughter. She is delighted with the phone, looked brand new and works perfectly fine; was able to transfer all the data from her old Samsung straight across to it, without a hitch! Thank you!

I couldn't be happier with my Galaxy S23 Ultra. I needed a phone with a decent camera to take quality pics for my new crafting side hussle that's becoming a business. My basic smartphone that was adequate enough for years became no longer fit for purpose. I've never felt the need to get the latest phone and regularly upgrade. Spending over £400 was a huge leap for me. But getting a phone that was top of the range relatively recently for a fraction of the price was a non trainer, so reconditioned is the way to ho for me. In very happy

I honestly couldn’t be happier with my purchase from Back Market. The Samsung Galaxy S23 Ultra I received looks absolutely brand new – not a single scratch or mark. The condition is way beyond my expectations. The phone itself is amazing and incredibly fast, and the delivery was surprisingly quick. I would never have expected a refurbished phone to arrive in such a perfect, like-new condition. I can genuinely recommend Back Market to everyone. This experience has completely exceeded my expectations!
