For 80 euros, I don't think it's worth the money. It has less space than another one I have (priced at 25 euros, same dimensions).
Of course, its plastics seem to be of good quality and its zipper as well.
I'm a little concerned about the wheels, as they go all over the place from the first use. Also, when you have it standing upright, it has a stability issue. These are problems you encounter in 20 euro suitcases. I really don't know if it's worth its money and surely if I could, I would return it, but unfortunately, I left Greece
