We've had this luggage for about 2 years now and have taken it on several trips and it's still holding up well.  I'm not a business traveler so it hasn't gotten what I would call 'heavy' usage but it has been used a lot more than what I would call 'typical' usage where people travel once or twice a year.  The only reason for 4 stars instead of 5 is that there are a few minor improvements that I could see being made that wouldn't likely make it any more expensive but would make it even more durable.  But since this isn't their top of the line product, they've got to keep something for the higher end models to differentiate.
