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.

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.

Not so happy. Phone was in a worst state of cleanliness. At least a bit of wiping needed. So many scratches and looks so old. l am not sure of functionality because l bought it for someone else. Very disappointing.
