Forget durability in today's flying environment. The big piece was checked in at 50lbs; sent to the plane side,; flight cancelled and was returned with entire bottom smashed in and unusable. The airline agency ultimately replaced it with another brand 30 inch spinner costing much more than the whole set but refused to replace the matching one of the three piece set; saying these Travelpro hardside spinners are their most frequently damaged beyond repair hardside spinners they have to handle!! I liked the two larger pieces' wonderful spinning action as I have problems in my shoulders from old injuries and want the ability to be able to handle when no help is around. They look nice however the carry-on got one big scratch on the top from being pulled out of an overhead bin removing the 'silver' coverring and revealing a black gouged material. Great price BUT in this case you are gettiing what you pay for. I am putting the other piece and scratched carry-on on an auction site with no reserve.
