The device arrived *very* quickly and is in working condition. However: the CMOS battery needs replacing (fine, not a big deal), the SATA cable leading to the additional storage enclosure was loose (OK, easy fix after all), and... the device has a different CPU than advertised. My order clearly stated "Core i5-8400 2.8Ghz", while I can see the device runs an Intel Core i3-8100T @ 3.1Ghz. For my use case, this is going to be just fine, and overall I'm still happy with the purchase, but if this is going to be a dealbreaker for you, beware.

It's in impressive condition for a refurbished item: in perfect internal and external condition, almost no dust, nothing suggests it's already been used for several years. I looked at the component statistics and it shows it ran for thousands of hours before refurbishment, but everything is in a state to last for years to come, all at a very attractive price. Thank you!

All correct, in very good condition, very well packaged and sent well protected. The computer works perfectly and I think the quality and price are right for what it is and what it offers.

OK, so: The PC arrived in economical but secure packaging. The shipping packaging alone made the purchase worthwhile for me. The PC itself arrived exactly as described and earlier than expected. I am delighted.

I've always bought from Back Market and I've always been 100% satisfied. This time, I'm very disappointed. I deliberately chose a computer for internet and office use, with Wi-Fi and Bluetooth as my main criteria. In the end, I received a computer that had neither Wi-Fi nor Bluetooth. When I reported the problem to the after-sales service, I was told that I'd been 'upgraded' from an i3 to an i5, which doesn't correspond at all to my initial requirements. Another problem is that the original advert has disappeared, so I can't prove that I'd selected a model with Wi-Fi and Bluetooth. I therefore advise you to take a screenshot of your order to avoid this kind of situation. That said, Back Market agreed to take the computer back without difficulty and will cover the cost of returning it, which I appreciate. I will therefore be recommending another computer in the same range, this time with Wi-Fi and Bluetooth. Despite this bad experience, I still consider Back Market to be a serious and reliable site, which I trust.

The fact that it came in French as the default language was a bit difficult for me to make the change. But otherwise everything is perfect so far (I've had it installed and in use for a week now).
