    (Note: The condition of this phone was listed as "excellent" in my original order, not "very good." My review is based on the original description). This is my second BackMarket purchase (previous one for an S22 for a relative). That experience was positive and was a factor in making another phone purchase, this time for myself. As previously, the search and purchase process was very easy. The phone was delivered very quickly and just as-described: in excellent condition with no noticeable scratches or cracks. With a little assistance from AT&T, I was able to swap my existing SIM card and then used Samsung Smart Switch to migrate all my existing phone data to the new one in about an hour. I've been using the S23 for about a week and no issues at all. I'm very pleased with the whole experience at BackMarket and would trust them for any future support and purchases.

    Perfect out of the box. Set up was a snap and knowing customer service was available if needed, was nice. This is our 4th purchase from Back Market and each transaction has been perfect!

    Phone never showed up. When I asked for updated info on the status of my phone two days after the expected delivery date, I wasn't given any information. I was sent a message stating that I would be refunded. There was no explanation as to what happened.

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.

20,341.2 gallons of water

That's like running a faucet for 3 days
