Bought two sets for a trip coming up in December.  Replacing two old sets and will report any problems after we complete trip.  They seem to be very sturdy and made good.  We'll see. Happy with what we know so far.

Ok got back from my first trip with it today and my update is as follows.  Left Tampa airport to Houston to change plane.  As the tsa tried to release the luggage pull, one side slide up what the other pull broke off at the handle.  Now the piece is useless.  Went into sale invoice and found out that since I bought it more than a month I'm screwed.  I really liked this product but what good is it when the seller doesn't back it up.  Have to buy another set and it will not be this one.  Further buyers beware and spend the few extra bucks.
