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! 👍👍

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 !
