    What an amazing experience it was. I read all the buyers' reviews before I made the purchase and was a bit feared. But the moment I received the laptop... Everything turned positive. It took me some minutes to find the scratches, it was so clean even in fair condition. All the other specifications were as mentioned but the charger is of Lenovo, which still does the job. But I might think of a refund as I was expecting a backlit keyboard which I read in the description as well, but this model doesn't have that. It will creat a lot of trouble for my work. Overall, it is recommended to trust this platform to buy refurbished laptops. Cheers.

    The ThinkPad is a little smaller than my previous machine, but I'm slowly getting used to it. Certainly, the Lenovo quality is first class. The screen colours are so bright and sharp, and the sound is excellent. I'm really pleased so far.

    It was just what I wanted and came the day earlier than predicted. I had a little issue not understanding that I could still use the Lenovo USBc power charger that came as I was expecting a HP one that matched the Laptop. But that all got sorted easily from my enquiry email and direct messages to the actual seller. This gave me piece of mind and I am happy with my experience.

    It’s brilliant the device is what I expected so fast and very reactive, the screen is so clean and interactive you know? The only issue I found is some key in keyboard needs a little hard press, that’s it, so ima rate 9.3/10

    It’s in such pristine condition, at first glance I would if believed that it was brand new! I also love that I’m able to play a huge game without running into any issues and fast loading times!

    I purchased a refurbished iPad for my Dad, who is not technical, and I was so impressed with Back Market. The iPad was in excellent condition and arrived well packaged, ahead of time, all for a very reasonable price. To date my Dad is very happy with the purchase and I will definitely use Back Market again.

    I read reviews which helped me to take the leap and buy my iPad and was not disappointed. It arrived in the condition described and is perfect for what I need! I really can’t fault it, or the service - ordered on Christmas Day, arrived 28th! I’m really pleased.
