I travel internationally quite abit and I don't know how I stood in the custom lines without spinner luggage! I am really impressed with the quality of this set. I first saw a Samsonite set at a local store but the set only came with 2 spinner bages for $150. My kids are thrilled that they get to use one when we travel too. Lots of space in all the bags and the smallest one is perfect for the quick one night business trip. The four wheels make traveling so easy and effortless! You will love this set.
