    Love the phone and it works perfectly other than it might have been an aftermarket screen and finger print reader doesn't work the best but it doesn't bother me the phone is amazing and an amazing price.

    Phone 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 👍

    Fast 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.

    I 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. I was left without a phone, and had no choice but to purchase a brand new one from the store, as I could not wait weeks for a replacement to come in the mail. I had to spend money I did not have, and lost a few hundred dollars by having to purchase brand new from the store, as well as losing my old device, as it's now still permanently blacklisted. I had no idea this is something that could happen. If you choose to buy refurbished, I'd recommend you contac...

Reborn vs. brand new

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

171.1 lbs of CO2e

That's like driving an SUV from NYC to Chicago.

6.3 oz of e-waste

That’s around the weight of a baseball.

537.1 lbs of raw materials

That's like 20 dogs digging in your yard for a week.

That's like running a faucet for 3 days
