    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.

    So far so good with the iMac 27". I needed a larger internal drive, but didn't want to spend an arm and a leg, so this refurbished 2017 iMac was the perfect solution. It is fast and i have had zero issues.

    Firstly, it came in the wrong color I ordered orange but it came in Pink. I can look past that because it still looks great. Now, it comes in an Apple refurbished box, but there is absolutely no wear and tear on the machine. Comes with all original Apple parts like keyboard and mouse which is huge! The keyboard itself is about 200.00 retail. It also only took one day to get me to with free shipping?? So although it’s the wrong color it’s still a 5/5 because it’s practically a new machine and it got to me in a literal day

    Back Market does an excellent job with customer service and did a great job responding to warranty issues. I would definitely recommend them. I was impressed. Remember they are handling your transaction with a 3rd party refurbishing company. They do an excellent job at that. The only issue I had was with the refurbishment company not shipping exactly what was specified in the listing but Back Market helped and I ultimately received what I wanted. Thanks!

    This was an amazing experience with Back Market! The refurbished iMac was carefully packaged and arrived quickly. The optional two year protection warranty provided the ease of mind when purchasing any electrical device.

    I’m super happy with my purchase, especially with the price being a fraction of what I would have paid for a brand new iMac. I’ll definitely be purchasing refurbished over brand new from now on!

    The condition of the iMac was incredible. However, upon set up, I had difficulty. I couldn't continue with the set up (for some reason) after connecting to the internet. The message indicated that I couldn't continue set up unless I contacted some organization and that I will be restricted from using apps/ monitoring. (Not exactly sure if it was me, or what) Well, I got nervous, Wiped the system and performed an Internet Recovery. Now it is up and running. I have had my eye on an iMac for sometime. Couldn't beat the price, condition or early delivery. I have purchased every apple product I own on backmarket. And often recommend it to others. This was the only experience I had that threw me for a loop. But I am certain I will be a returning customer.

    iMac is great with no hardware issues! Only issues are cosmetic such as the scratches being very noticeable despite ordering excellent condition. The keyboard is also very cheap feeling so I ordered an Apple Original keyboard. Definitely recommend buying this Mac.

    Very happy with my purchase.My "used" IMac looks brand new. Customer service is great. Delivery was quick. My only disappointment is that I made an assumption that it would arrive with an Apple keyboard and an Apple mouse. It didn't and iinstead got a functioning universal pair, would work for PC or Mac. I wanted the familiarity of the Apple products, and luckily had a spare.
