A device that "fulfils" my wish of not having a "tablet" in my pocket. Very satisfactory condition even with this correct mention. Really prompt delivery (less than 24 hours!) even though this option was not ticked. Second device ordered from you and still satisfied.

This is my 2nd experience with Back Market, delivery ahead of schedule! Getting it up and running went very well. The only downside was that I hadn't thought to order the appropriate protection and I had a lot of trouble finding it!

The product is as described and expected . The service and contact is great . I find shipping with FedEx a bit inconvenient because you have to be at home for delivery. DHL would have worked better for me.
