I 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.

I 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.

Great . I had a Samsung Galaxy A54 work phone ,which I liked. I've recently retired and needed a replacment phone .I decided to get another Samsung . The phone is in great condition and the Web site is really informative and detailed in helping to choose a handset. I'm really happy with the entire process. My wife is currently in a phone contract. She is going to purchase a refurbished phone next time.I can only speak for myself but ill definitely check out Back Market when I purchase my next phone

I was a bit nervous purchasing a refurbished phone, but a friend of mine had previously had an iPad from Backmarket and was very pleased with her purchase. I'm glad I went ahead with the purchase, as I'm really pleased with my phone. Thoroughly recommend.

Delivered quickly. Perfect condition, as advertised. Replacement for the Wifes old S9+ phone, fully up & running with account details swopped over in about 10-15 minutes. I always buy refurbished to cut costs. 5-star.

The phone is in excellent condition no scratches.! Bought as present for my mum, very happy with the phone but maybe because it was refurbished everything needed updating, with back up and transferring everything from her old phone took about 4 hrs to set up but supper happy with the phone.
