I was very skeptical about making a big purchase on something like this on here because I saw mixed reviews but more recently I was seeing nothing but good reviews so I took leap of faith and made the purchase. I couldn’t be more happy with my iMac, it came in excellent condition as stated with Apple certified refurbished it looks brand new and works as good as new. Would definitely recommend!!

And I did not see any reviews mention it! And it also still has Apple care on it!! I am so excited! 😆 love my new iMac set up!!

I was so excited to get this in the mail, it was packaged so beautifully in the original packaging. I screamed when I opened it. It was everything I’ve ever dreamed of. I love ordering from BackMarket. I’ve always wanted a Pink iMac and because of the price I was able to finally own one. I couldn’t be happier.

iMac came in original box with everything secured. No scratches looks like new! Startup was quick and easy, shipping updates were clear every step of the way. Always recommend Back Market for any tech needs!

Wonderful. Came with a generic keyboard and mouse, which I was not expecting but maybe that's on me for not reading the fine print. Everything else is fantastic. Computer works great and is in good condition, which the exception of a small chip on the top front corner of the screen. You can't tell unless you knew where to look. I will most likely be purchasing another refurbished device from here in the future and definitely recommend this site to anyone looking to get a new iMac for a great price!

After ordering a similarly advertised iMac on Amazon, I chose to go to Back Market. The other refurbished iMac was wrapped in bubble wrap and came with non-Apple accessories (keyboard, mouse, etc.). I was disappointed immediately, but that disappointment turned to frustration when the iMac did not even power up. After returning that unit, I went to iMac and received a like-new pre-packaged iMac with all of the same bells and whistles you expect from an Apple product. It was as close to getting a brand new iMac as I possibly imagine.
