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.

Very happy with the purchase. We felt confident that Back Market have provided us with a phone in great condition that has been refurbished. The warranty and additional cover available helped us to buy from them knowing that we have support should we need it.

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.
