5/5Firstly this was a replacement for a previous purchase that had developed a fault. The process was excellent, a replacement mobile (this model) sent immediately and pre-return. The classification was upgraded to premium from excellent; apart from having to reload everything from the original phone (bearing in mind the newer one was faulty and could not be used) we packaged the faulty model and returned using a pre-paid address label. The new phone is excellent so far, nothing but praise for the process. The only point raised is if such a fault develops (phone completely frozen) taking to the internet assisted us (we hope) in deleting the memory of the failed model. When things go wrong, good and speedy service goes a long way to reducing disappointment, we have received an excellent service and are happy to recommend the process!

5/5I bought the Galaxy S23 for my dad. He is really impressed with the speed, the long battery life and the camera. He said the phone works like new and he would never have known it was a refurbished phone if I hadn't told him.

5/5My old A10 was getting very slow so decided to get a newer samsung. Several family members and friends recommended Back Market so decided to give it a go. Wesite easy to use to enable you to pick the make and condition of a refurbished phone. It arrived the following day and was exactly what I had ordered. Transferred all my photos etc and so far am thrilled with my new refurbished phone. 😃

5/5I recently bought a refurbished Samsung Galaxy S23 from Back Market, and I’m genuinely impressed. The device arrived in excellent condition — honestly, it looks and feels almost brand new. The screen is flawless, the battery health is strong. I have placed the order on Sanday morning and I received on Monday. Back Market’s packaging was secure, delivery was quick, and the whole process felt smooth and reliable. I really appreciate the transparency about the device’s condition and the warranty included, which gave me extra peace of mind. If you’re considering a refurbished phone, the S23 from Back Market is a fantastic choice. Great value, great quality, and a much more sustainable way to upgrade your tech. Highly recommended.
