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.

The case is solid. It feels very protective. The only issue I have is that the buttons are a bit stiffer now. I have arthritis in my hand so its hard to change the volume with one hand. Other than that, I can trust my case to protect my phone when it falls on things other than my face.

I used to have a phone that I wouldn't wish on my worst enemy, so to say it was a major upgrade is an understatement. The site was easy to use and the prices are amazing. I know it sounds like a review left by the marketing department, but I seriously love my phone so much.

The IPhone 14 I received looks like a new phone very little signs of wear getting it set up and transferring my data from my old phone was relatively easy getting it set up through my provider and keeping my same number was also easy and quick overall I am very satisfied with this purchase

iPhone 13 128G- I bought this in “fair” condition but that was incorrect. It looks like a brand new phone! 100% will recommend over and over and when it’s time to upgrade again, I will be back. Also got a very sturdy case and it’s already proven it’s worth.

The case is awesome; fully transparent, tight fit, and it looks like it will be very durable. The screen cover, as carefully as I followed directions, does not stick around the edges. No sign of dust or dirt, I suspect the adhesive just isn't very good.

I purchased a Samsung Galaxy 21+ and a case to match. I was impressed with the price and indeed the product was received in good time, in good order and I was quite satisfied. I also made an arrangement to trade in the old phone for $4. When the time came to complete the trade in agreement, I was asked to enter my bank routing number and my account number at said bank. My decision was... No one in their right mind would give that kind of information to, pretty much ANYONE. Much less a brand new startup with unproven history. Call me whatever you wish but that was just a ridiculous request.

"I ordered 2 by mistake and cannot find a way via your online support that will allow me to return one of the cover sets !! I have been trying numerous ways to reach out to you but your forms do not allow me to select the correct reason for returning one set."

The condition of the phone was perfect and shipping was really quick. The only complaint was that iTunes was needed to update to iOS18 which isn’t supported. This did cause a delay in getting the phone set up but this is an Apple support issue not a reflection of back market.
