I was not convinced a refurbished was the right way to go. I needed a new phone to operate my insulin pump. The phone I got looked brand new and works like it too. After running my pump all day, texting and phone calls I still have 75 to80% battery life. I would not hesitate to buy electronics of any kid from Back Market!

Everything appears to be working as described. I was disappointed there was some scratches on the screen, however it could have been worse since this is refurbished. Phone has been working well and meets my needs. Thank you.

Quality of this purchase for otterbox iPhone mini 12 case : is a 10 out of 10 especially for being a refurbished case I can’t even tell that it’s been refurbished, it looks brand new. I love how slick this otterbox case is, phone just slides in and it grips the phone around the sides perfectly. It was delivered extremely fast as well. Thank you back market!!

Product was as advertised, and worked well. Price was very reasonable for a refurbished unit, and it felt good to remove one item from the landfill for a bit longer service life

Came quicker than expected, and is better than I thought it would be. I thought this would be pretty bad, but ended up being pleasantly surprised by the immaculate quality of the astonishing product. I honestly couldn't discern it from a brand new product as the refurbishment was done so skillfully that the product couldn't be considered of any lower quality than that of a brand new one if you were to be judging them with the naked eye.

I am so glad I found Back Market! I desperately needed a new phone but didn’t want to buy the newest iPhone. I believe that refurbished is the way to go and I will never buy the newest phone again when I have this awesome website!

The customer service was great however the actual quality of the case and screen protector aren’t. The case seems to be melting on my phone and the screen protector scratches and cracks easily. I would recommend getting a screen protector and case elsewhere, but I would buy from here again

The iPhone 14 Pro and case aren’t very good condition, but the value of my iPhone X was supposed to be $76 when they reviewed my phone at the shop. They offered me $7. I was told to take pictures of my old phone and tell them if anything was wrong. There was nothing wrong with the phone and the outside condition was perfect. Not one chip or crack but when they reviewed the phone, they said my operating system had problems. how am I supposed to know this as a civilian in the world. I don’t have a diagnostic machine to run on my iPhone. in conclusion. Don’t promise me something and turn around and rob me blind. That’s some shit thing to do to somebody. Seven dollars, screw your seven dollars

Everything that I expected. No surprises. I am glad you exist, as I prefer to purchase existing items that are usable, rather than creating demand for new items. Thanks, and I will check back with you when I need something else! Dennis Mark
