The Cox Swain Trolley CABIN has now been used by me on several business and private trips. Processing seems very solid and the format has been accepted without any problems at all airlines. For acceptance by Ryan Air, I can not tell anything because I am not yet flown with this airline. The rollers show so far a good quality. Price paid by me I found quite adequate, the delivery was fast.
Particular useful I find the laptop compartment inside the trolley, I use it like for my service laptop. By four short, fitted with snap fasteners straps around the trunk, can be this close well even at high capacity and you have no feeling that the zipper could tear at any moment.
Overall, I think is a good buy, I would recommend without hesitation.
