    I absolutely love the phone I purchased through backmarket. I purchased the premium grade phone and it is totally flawless. I thought the battery life would have been premium and that's the only negative. the phone itself works perfect and doesn't have a single flaw. I paid a great price and helped mother earth by buying refurbished. Every device I purchase in the future will be through backmarket.

    It feels great buying a refurbished phone & not buying new. It's a great phone but one thing is my charging port is weird & flicks on & off charging

    Ordered phone in excellent condition. Came in exactly as advertise, fully functional along with a cable and brick. Overall happy with my purchase and new upgrade of a phone. 2nd time buying from back market and likely won't be the last I will recommend!

    Great service & prompt delivery. The phone had a few very small scratches but works perfectly. The delivery box was torn slightly open, but there was an inner box & nothing appeared damaged or missing.

    as usual, everything went well! the s24 ultra is a huge upgrade and was in better condition than I was expecting. the savings versus a new phone alone was well worth the purchase, and it arrived on time =)

    My phone was shipped quickly, it was packaged very carefully. The packaging is reusable. I was so pleased to see that my phone was in "like brand new condition ". The price was extremely reasonable. I was also very happy with the amount they gave me for my trade in. Back Market also makes the trade in process so easy. I reallyvlove my Galaxy 24 Ultra!! I will definitely use Back Market again in the future.

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.
