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!!

I ordered in excellent condition. The product came perfect. Arrived in an apple certified refurbished box. It also came with a third-party keyboard and mouse, I ended up using my mouse and keyboard from my older iMac. But the third-party once provided work fine. I went through all of the settings, everything is exactly as it's supposed to be. Not a single scratch. Very satisfied with this purchase. Also I order on the 7th and it arrived on the 10th. It was originally estimated to arrive on the 14th but it shipped out the same day I ordered it. Very fast delivery.

Everything came in earlier than expected! The iMac was in the original box!! Came two days earlier than expected! I also want to add that the IMac comes with a Magic keyboard and Magic Mouse! 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.

I recently purchased the 21.5-inch Retina iMac (Early 2019) with a 3GHz Core i5 processor, 128GB SSD + 1TB HDD storage combo, and 16GB of RAM—and I’m seriously impressed! It came in excellent condition, and everything works perfectly right out of the box. I use it daily for school and work, and it’s been nothing short of reliable. The screen is absolutely stunning—colors are crisp, and everything looks incredibly sharp. The built-in camera is clear, and both the keyboard and mouse were included and in great shape. I was also pleasantly surprised by the volume quality—it’s loud and clear, perfect for Zoom calls or just streaming music while I work. Overall, I’m super happy with this purchase and will definitely be returning to buy from them again in the future!
