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.

Great service, and a great phone too. Much better to get a quality refurbished phone than jumping on the "latest tech" bandwagon. Thanks guys! 👍👍

Hi, Samsung galaxy S21 is great phone, no scratches in great condition. Travelling soon for a long time, bit worried about having to charge it all the time, that's what happened to my Samsung galaxy S11.

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.
