The visible condition is like brand new. Nice to have the same model as before, but with higher gigs. Cable transfer from old to new did not work, but wireless did. I still have work to do transferring 2 factor authentications.

I love my "new" phone. It feels so good that it's recycled at a fraction the price of a new phone, reducing waste, AND the phone is like new - not a scratch, and the functionality is guaranteed. I ordered express post for only $8 and it arrived in 2 days. Back Market was so efficient, it was carefully packaged with a a cable. I recommend Back Market and will use them again - eventually !

Brought a s21 for my daughter. Being the good condition option we were expecting a few scratches on the body and screen, to our surprise it was in perfect condition. The battery was dead when it first arrived which we liked so we could fully charge it right from the start. It holds battery well. She only has to charge it every second day and is on it quite a bit, as with any teenager. Delivery was also really quick. Came within two days of ordering. We will definitely be buying from here again for future phones and maybe other products.
