    it's amazing, I didn't know if I can trust in this, I saw some ads before, so I decide to look up for something here and see if it makes me try if it's worth or not, so I bought the flip 4 in excelent conditions, it is perfect, you can't even tell is refurbished, I would recommend the app, so trustable, just make sure to read the expecifications of the product.

    I ordered the item on a Tuesday morning and it was delivered by Wednesday afternoon. Phone looked brand new- no marks (I purchased Excellent condition). Super easy set up process and so far so good. Everything about the pone seems new and you would never tell it was refurbished. Love the peace of mind of the 1 year warranty. I will 100% recommend back market to my family when we are in need of another phone.

    My first purchase from Back Market and won't be the last! As soon as it arrived (about 3 days), I opened to find my phone neatly placed inside and great packing material. I was overall impressed with the quality of the device and has not given me any issues whatsoever. I will be looking forward to my next purchase! I love that this exists and such a great way to keep e-waste down! I will be continuing to go here for all refurbished devices.

    I ordered the galaxy z flip4 256gb dark purple, I was very excited to receive it earlier than expected, I set it up with my network and I am so happy it worked immediately, I tried 2nd hand phones before, but all disappointments, I am so glad I found you Back Market, you guys rule, the phones are practically brand new, and ran like new, very very satisfied, I will be shopping from you again whenever I want an upgrade. Thank you back market

    Buying experience on Backmarket is superb. I got the Galaxy Z Flip4 256gb in perfect condition for 1/3 of the price. Only down is that the battery does not last as long as if it was brand new, but it can still hold a full day of normal usage.

    i got this because i quickly became sucked into the gimmick of the flip phones. it has quickly become my daily phone!! (: i really like how small it is, i tuck it in my pocket at work and i like accessing the media player from the cover screen without having to open the phone. the battery is of course, lacking compared to my s23+, but i quickly got used to it, and it still gets me through a full day's work. although i got the 'good' condition, i didn't notice any blemishes of any sort, and it works just fine pairing with my watch 4 and samsung buds. thank you very much back market,i took a chance on you guys and i'm very satisfied 😌

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

That’s around the weight of a baseball.

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