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.

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 !

Delivered so quickly! My phone is working very well, learning the new things. Perhaps a few more scratches than I was expecting but it works really well. The charging cable sent necessitated my purchasing a compatible plug...
