Excellent quality and amazing value! The iMac came in its original box with all Apple colour coded accessories, including an ethernet port on the power brick. The new MacOS Golden Gate also works fine, no problems.

The condition is excellent, as stated. It works perfectly for my Lightroom editing. I'm in love with it. It genuinely felt like a new iMac when I opened it.

Immaculate quality! I ordered this Mac and the initial device I received was not the condition I expected, however I could easily exchange this and a new Mac was sent to me next day which was EXCELLENT. The exchange was so easy and prompt responses for the customer service team. I AM VERY HAPPY WITH MY NEW IMAC. I just want to add, you do not not receive the compatible iMac keyboard and mouse. I purchased these myself through apple and have connected them to the computer with no problems. 10/10 would repurchase a product form back market again.

My iMac is in truly excellent condition, was so easy to set up from my other iMac and is a joy to use. Delivery was really quick and it was packed extremely well. This is my third purchase from Backmarket and every one has been excellent.

The mac itself works well and arrived in good condition, but alot of the keys of the keyboard don't work and the mouse times out after 2 ish minutes so you have to keep clicking to get it back on which is annoying, So will probably replace these. I came from not having an Imac or macbook so the software has been a challenge to get used to, even though I have an I phone and I pad. But no fault of backmarket so still overall happy with my purchase.

The iMac itself was as advertised. The condition was excellent and I was able to migrate from my existing iMac to this one without problems. It was delivered in original packaging quickly and efficiently. The reason I’ve given 4 stars rather than 5 is that the keyboard and mouse supplied were not Apple products, and I don’t think this was clearly stated in the listing. The mouse provided was of reasonable quality, but the keyboard was small and plastic - it didn’t hold still on the desk when I used it.

iMac arrived in perfect condition was very impressed the only problem was that it had arrived with a US plug and we had to go and buy worldwide adapters which were harder to find in the shop - very impressed with the iMac itself though
