I ordered this hand luggage as I was travelling with Ryanair who have the smallest luggage allowance (that being only 20cm wide is allowed). I was a bit wary when it turned up as the pocket on the front makes it larger than 20cm, plus it's very flexible, so if you're travelling with Ryanair, just make sure you don't overpack it or you may fall foul to them charging you extra at the gate!
Overall, VERY HAPPY with the luggage, it's made from good quality materials, the joins in the material feel strong, the zips are good quality and the handles (including the extendable handle) feel strong. The great thing too is it is MUCH lighter than a lot of other luggage the same size - who wants to use their weight allowance up with luggage itself?
Highly recommended especially if you're flying with Ryanair, but watch out for that front pocket, don't overpack it or you may go over the size limit for cabin luggage.
