    Amazing! I ordered this iMac because of the heavy specs and great price and I am not disappointed! Item arrived a little later than advertised but was delivered in A1 condition. This iMac came in an original Apple box with original Apple wireless keyboard & mouse and had the smell of a new car, yummy! Took it for a road test and the specs are exactly as advertised - the entire unit and accessories are in EXCELLENT condition (just a couple of minor scratches on the base stand which are barely visible). I'll never buy new again, refurbished tech is the future people! Happy customer :-)

    I have come to live back market, the products are always fantastic and even if there is an issue they sort it out really quickly. I prefer to buy refurbished as it's more eco friendly and that's exactly what back market stands for which is fantastic. high quality goods at cheaper prices and eco friendly, can't fault it at all. my only issue is that the descriptions could be much clearer. as a person with dyslexia I struggle to read black text on a white screen and I misread so ething which was disappointing but the customer service was fantastic and it was sorted really quickly. I am going to be ordering phones for my teenagers very soon as Christmas isn't far away and I'll definitely be buying them from back market.

    High quality machine, refurbished to a really good standard. I'm still moving stuff from my old machine, which is taking longer than I had hoped - shows how old my original machine is. Super fast delivery, and good communication. Really happy with the service received.

    Incredible service! Received my computer 2 days later, which was a few days before it was due - so I am beyond happy! Computer looks brand new - as if it was brand new and not refurbished. 100% recommend!

    Always wanted an imac. Decided to go with back market and had an excellent experience. The computer showed up promptly after two days in the original apple imac box. On inspection the computer was spotless like new and runs and works perfectly. I'm so happy I chose back market for my purchase.

    I am quietly ecstatic about my 21.5” iMac! Almost set itself up on its own, it’s squeaky clean and unmarked. I’m less chuffed by the keyboard and mouse combo, a bit plasticky and a bit of a faff. The rechargeable battery is useful but not enough for me to fall in love. On the other hand, my old ally-cased Magic Keyboard and keypad works perfectly so no probs. All in all, you’ve played a blinder: well done!

    Thrilled with my IMac, had been thinking about changing my old one for a while as it was getting very slow and freezing but the cost of a new one was daunting. Was recommended Back market by a friend. Delivery was as promised and it is as good as new, couldn't be happier.

    The iMac was very good value at £190 for a 10 year old computer. The screen and keyboard were in good condition but the Mighty Mouse trackball is gunged up and will only scroll down. The screen resolution is a bit blurry compared to the newer models but that's just showing its age. I can only run Macos Catalina which is a bit disappointing as it is a long way backwards from Sonoma. Maybe your specs could be more accurate instead of saying: "will run the highest OS supported" and leaving us to guess what that could be. Overall very good value and I'm still a big fan of Backmarket.

    Very happy with my new purchase! My iMac is like new, even came in what looked like the original packaging. My iphone is going to need replacing next, and I will not be spending un-necessary money or beating the planet up any more by buying a new one after this experience!

    It works like a dream and will keep me going until apply cheer up and deliver a new 27” imac. Just one thing, what is that silver disc on the front for, it spoils the look of the machine and shows the only sign of wear which is a shame. Price great and delivery very swift.
