Love these suitcases. Had the Blue set, took them to Europe changed 6 different planes. Wheels worked perfect in airport and streets. My fiances different brand broke down half way through the trip. Only issue was airlines scratch them up a little, so bought protector covers for new set. We also bought my fiance the silver ones. We cant wait to go on our next trip. My son loves the blue set we gave to him. Everyone is happy all around :) A great buy. Came in a timely fashion too.
