    I ordered the S21 Ultra in the GOOD condition and as far as body work, there were like 2 small scratches that were not noticeable at all at first glance. The screen is flawless. For the price, I am beyond satisfied. I ordered it on a Thursday and it was delivered Saturday at 10am. I received constant communication and updates from Back Market. 5 stars all the way around.

    I have purchased my last new phone. My last two phones have been purchased through Back Market and I couldn't be more satisfied with my experiences! In the past I went with an unlocked phone. However, this time I knew the carrier that has the best coverage in my area, so I went with one locked to that provider. This saved me some over the unlocked version. Additionally, in the past I went with one in "Excellent" condition. This time, the best value at the time was for one in "Good" condition. I thought I might regret it, but the savings at the time were enough to sway me. I have zero regrets! The phone is in great shape! The battery life also has exceeded my expectations! And the camera is exactly what I hoped it would be! At whatever point in the future I feel a need to get a different phone, I already know that it will be one from Back Market!

    Bought product in good condition, and received a like new phone. After a day I noticed a small scratch on the back, but I think that was me as I immediately dropped my phone the first day. I blame myself. I haven't tried to activate it yet, but I ordered a Verizon locked phone and it showed a Verizon logo upon turning on, so it looks like all is well there. Overall I am already recommending my friends to check this site out...very happy with the price and especially the condition of the phone. Check Back Market first!!!

Reborn vs. brand new

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

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.

20,341.2 gallons of water

That's like running a faucet for 3 days
