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!

Totally satisfied with my purchase. It is a top rated Which? reviewed phone, Samsung Galaxy S23 Ultra. Promptly delivered and in perfect condition and working well. Many new features that my old phone did not have, so I feel it is a really good upgrade - I got it from Back Market for a brilliant value for money purchase price. Love that it is refurbished too. It's an added bonus that the carbon footprint is so much lower than a new phone. Refurbished to this specification is always best. Really appreciate the ethics as well as the product, many thanks.
