I recently bought a used iPhone 12 and the transaction was perfect.. The phone I purchased was listed as being in "good" condition according to Back Market. From what I could tell the phone is in better than "good". It works great. On top of that, the device was delivered 2 days earlier than expected, which was an added bonus. I couldn't be happier with my purchase from Back Market. THANK YOU BACK MARKET!!!

Backmarket has incredible customer service, and once again, they wowed me. This phone is in better condition than anticipated and by buying my own phone, I was able to escape my expensive cell contract and switch to a $15 a month plan that works perfectly for me. What’s more, I got way more than expected in a trade in for my old phone, which was functional but totally smashed. Thank you Backmarket and your amazing network of refurbishers. I tell everyone to shop here.

I purchased a locked (T-Mobile) iPhone 12 that was listed as "good condition". I received it in 3 days, and when I opened the package, I found a phone in pristine condition! Not a single scratch, either on the front or the back. The battery must have been changed because the max. capacity of the battery is 100%. The switch from the old phone to this one was a breeze (works with the SIM card). I saved $150 compared to purchasing a refurbished phone from Apple. So far, I am super happy with this purchase.

Phone was in impeccable condition, no scratches or dents. Battery life is 90% as expected. No issues with it at all. Shipping was also speedy and on-time. Will definitely consider using Back Market again!

For a refurbished iPhone 12, I would say the condition of the condition of the phone was "Excellent". There were only minimal scratches on the screen. Battery Health was 97%, which is awesome for a phone made in 2020. The phone looked and worked great. However, I was sent the wrong phone. I ordered a phone that was supposed to be locked for T-Mobile and I received a phone locked for Xfinity Mobile, which uses Verizon. Being that only the original Xfinity Mobile account owner can unlock a phone, I could not use this phone. Very disappointing...I guess the seller cannot read and understand order requirements.
