The iMac screen/processor is good. Communication above par very informative and helpful prior to delivery. Packaging & delivery good. Really disappointed and very surprised, keyboard & mouse not Apple products, both are Usb A connectors while Mac has four USB C. Mouse has Usb A dongle, keyboard is wired but with USB A. Not good enough. Not good enough

It is perfect, fantastic, really like new and in excellent condition! Sturdy, well-maintained packaging containing its original (expensive wireless ...) box and accessories. It works very well. For my taste and habit I preferred to connect my old extended wired keyboard and magic trackpad 1' series and switch the new ones to the old '15 iMac. Extremely high performance specifications. Description and promises kept. I am fully satisfied. Buy in confidence!

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.

I am very satisfied with my purchase. Delivery made in less than 4 days after online purchase. IMac in perfect condition with original box, keyboard and mouse. After starting up the imac, it notified me that the screen had been replaced by an original Apple part. I have nothing but good things to say about my first experience of buying refurbished with Backmarket.
