I don't know about their rollaboards, but the other Eagle Creek products that I've used are great. They have a lifetime repair-or-replace warranty, and they take it seriously.

Their gear is very durable - the bag I use on almost every trip is an Eagle Creek travel pack that I bought in 1987, and it's lasted through some pretty rough travels. I've sent it off for repairs/refurbishing three times since then, and it has always been sent back in excellent shape, with small gifts (luggage locks, etc.) included each time. All in all, a great company IMO.
