I travel for business and average over 230 days on the road each year. I've owned one of these for over 3 YEARS!!!! It has been on over 350 aircraft and endured everything the airport gorilla's can throw at it (or I should say throw it at). I am not easily impressed. However, normal suitcases only last me about 3 months, if they are good ones. I'm impressed!!! My old one has been around the world several times. I just bought my second of these and it isn't to replace my old one. I just want another because I use 2 bags. You will love these. They keep everything dry, secure, and last like better than the energizer bunny. I only gave it 5 stars because I couldn't do 10.
