Not sure if you are referring to the ones they call "Action Packers" but I have been very pleased with their use and durability. They are just within maximum free allowance dimesions and have proven very durable...I have completed many an international trip with them. If I am travelling to many less developed countries where theft in an issue I prefer these to more expensive luggage as it slightly reduces the chances of having something stolen.

I always go with extra tape in my carry-on for when TSA is outside - when inside TSA was nice enough to tape my Auction packers up again doing a great job of it too.
