We have had our bugaboo frog for 1.5 years now and travel a lot (flying). We were recommend by friends and family not to buy this bag, because it was not worth the money. What a mistake! Our bugaboo got damaged everytime we travelled, every time a little more in our non-branded cheap, good-for-all, stroller bag. We flew this weekend and the bag was convenient, easily fitted all parts and our stroller was spared the exposure of bad handling by airport personnel. The wheels are perfect, easy to take it along, together with a suitcase. Can't think why we didn't buy this sooner!?!
