Grabbed a couple of their packs when I was in the US. The warranty is fantastic, which is fortunate as one of the packs didn't last a week before a strap fell off. That same pack also had it's waterproof zip give up the ghost not long after. By that time I was back in NZ, and sending the pack back to the US for repair would cost more than I paid for it.
The little reactor day pack is a different story altogether. It's seen a lot of use when out looking for deer, and most nights to carry the battery for my rabbit / possum shooting light. So far it's standing up very well to the abuse, and I wouldn't hesitate to grab another.
