    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.

    So far everything seems good with the refurbished IMac I purchased. It was listed as excellent condition and does in fact look that way. Shipping was pretty good. Back Market seemed to have the best price for what I was looking for. Overall very good experience and would recommend shopping here.

    I'm coming from a Microsoft desktop so I'm trying my best to adapt to my "new" mac. I like it so far but I'm concerned about this Fusion Drive. I still need to contact the refurbishing company for details but overall I feel this will be a big improvement for me.

    BackMarket - you really know how to deliver on your promised products. My iMac Pro arrived a few weeks ago in immaculate condition and works perfectly. Also the included refurbished Apple keyboard and mouse was the icing on cake! Beautiful. Great work! I've been using Apple Mac's for 30 years, and BackMarket's refurbished Apple Mac computers have me thinking about my next Mac, right now. IP Attorney in Darien CT

    I always love buying things from Back Market! Their website is awesome and easy to use. I also love my new (well, newly refurbished) 2021 24” iMac! It runs really well and obviously blows my old 2009 out of the water. The only downer is that it has so little storage space, but I just added an external hard drive and it is a dream. It looks brand new too. I picked one that was “Excellent” shape and it truly is. I am very happy with everything about my purchase.

    The iMac came in excellent conditions and it works smoothly, however the mouse and keyboard that came with it aren’t Apple products which I expected but they take forever to connect and they also disconnect in the middle of using them.

    Purchased this machine to replace my nearly decade-old iMac, and couldn't be more pleased with it. My old iMac was a 2015/32GB/i7, so was initially leery that 8GB would be underpowered for my graphic design and photo editing work. Turns out my fears were completely unfounded - with the M3 processor, this new computer outperforms the old one even in its heyday. The mouse, keyboard, and cables it came with all appear to be brand new. It was shipped in secure packaging, and arrived quickly considering the distance it had to travel. For a fantastic price, I received a blisteringly fast, cosmetically perfect computer that functions beautifully for everything I need it to do. Hoping to get a decade out of this one too... but will 100% purchase from this seller again when the time comes time to replace other apple products.

    Computer arrived earlier than expected! Packaging was great and quite ingenious. Didn't inspect with a magnifying glass as case blemishes don't matter. If there are any on the back it is okay as I turn that side away from me (!). Keyboard and mouse are not high quality but work just fine. Set up instructions for these are a bit convoluted but went smooth enough. Will probably swap the mouse with my Apple Magic Mouse from my old outdated iMac. If you use ethernet for a network, be advised the ethernet port is in the power cord brick. The computer didn't come with any manual but a quick search gave this old man the answer. I highly recommend this computer in whatever color of your choosing. Purple looked the softest on my eyes when looking to buy and it is very subtle. I had previously purchased an older iPhone as a replacement for my wife's (which is how I found Back Market) and it was flawless. Didn't hesitate to see if they had an iMac. I highly recommend and will do more business in the future. I have told my one friend and the dog next door. Doing my best to spread the word. Keep up the great work Back Market!

    I purchased an iMac that was rated in excellent condition. It's not exactly in brand new-like condition, but it's acceptable. The performance is as hoped, so, all in all, I'm satisfied with my purchase.
