Absolutely delighted my galaxy A51, great interface and amazing storage. Only downside is the battery life compared to my old Samsung galaxy J6, but the performance of the phone outweighs the downside by quite a bit so overall I'm happy. 😁👍

The Samsung A51 I purchased was described as being in 'Fair' condition so I expected scratches and dents etc. it actually looks almost brand new. The battery does run down quite quickly but will last a day with normal use so not a problem. Overall I'm very pleased with my experience with Backmarket.

This is actually the third phone bought from you. Each one has been in very good condition until my teenagers have got hold of them anyway. On this occasion the phone looks new and my grandson is very happy with his new Samsung.

Brilliant service and fast delivery- well packaged and arrived safely. This is an emergency phone having experienced some issues with swapping phones/providers. As such, the phone is showing its age from a performance point of view, but it is 4 year old technology, so hardly likely to keep up with the current top end phones. All in all, its got me out of a tight spot, and and an affordable price. I can't wait to get rid of the phone to be honest, but it plugged a gap for a short period of time.

I was recommended to use Back Market to replace my mobile by my husband, who had previously utilised your services for the same. What an excellent service I have received; everything has surpassed my expectations and I will definitely recommend you to others 😀.
