    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.

    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!

    I received what I asked for. I asked for a refurbished iPhone 12 in good condition. That’s what I received.
