Verified purchasePhone came super early. The package was in mint condition (not crushed like other stuff I get from fedex). The screen was scratched, but for an "acceptable" phone, there wasn't much damaged. Everything works perfectly đ

Verified purchaseFast shipping and the phone i received was actually in better condition than I expected. The only negative thing I can say is that the charging cord is received wasn't for this particular phone. it was an older style cord rather than a type c cord. Other than that, I'm very happy with the phone and the service.

Verified purchaseI was sold a device that was reported stolen. I was issued a refund swiftly, and without further issue, however, the ordeal still caused me a massive headache, and a lot of lost money, that would not have occurred had I chosen to purchase from a different seller. I only found issue with the device I was sold when I put my SIM card in it, and found that it would not activate. I did not know the cause, so I returned my SIM to my original device, and suddenly found that now that phone doesn't work either. I had to call AT&T, and even drive to their store to find out that I was sold a stolen device, and that by putting my SIM card in that device, and then back in mine, that my phone was now permanently blacklisted from my service.

Hereâs what you help prevent on average by choosing a reborn smartphone over a brand new one.
