    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.

    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.

    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 Will probably swap the mouse with my Apple Magic Mouse from my old outdated iMac.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!

    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!

    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.

    As with my other Back Market orders, I'm very pleased with this new computer. It is in excellent condition and functioning great. The only item I'm disappointed with is the keyboard. It will not sync with the computer and feels kind of cheap. It's fully charged and turned on, but does not appear in nearby devices to pair it. I've tried a few things, but just don't have time to figure this out. Using an old keyboard for now, but the wasted time and money (as I'm sure price included a working keyboard) definitely negatively impacts my Back Market experience.

What is a refurbished iMac?


A refurbished iMac is a pre-owned Apple desktop computer that has been restored to its original condition and performance by professionals. At Back Market, we handpick each and every one of the sellers on our platform to make sure you're getting the best refurbished iMac available. The refurbishment process typically involves rigorous testing, cleaning, and repairs, so that the computer meets the same standards as a brand new device. So when you buy refurbished you're basically getting a new iMac at a discounted price.

iMac warranty and return policy


All iMac purchases on Back Market come with free standard shipping, a 1-year warranty, and a 30-day money-back guarantee. We want to make sure you can shop with confidence and find the best Apple computer for your needs at lower prices.

 

What to expect from your refurbished iMac


If you're buying a reconditioned iMac for the first time, you might not be sure what to expect from your purchase. First, understand that your Mac may have cosmetic flaws depending on the condition you choose (Back Market offers devices of Fair, Good and Excellent quality). However, whatever the condition, it's important to know that any external blemishes will not affect computer performance and you can expect your device to perform as if it were newly opened directly from the Apple Store. You should also be confident that your iMac computer is backed by a 1-year warranty, meaning in the rare case that any defects arise (outside of accidental damage) within 12 months of your delivery date, then you're entitled to your choice of a repair, replacement or reimbursement.
