We bought 2 of these after we got married because we figured we needed some decent luggage for a honeymoon, etc. First off, I am really impressed with their warranty, which covers airline damage. I've been fortunate to never have any real problems with airline damage, but the piece of mind is comforting.
Pros: The wheels feel sturdier than most competition. I used to have a carry-on size bag (Samsonite) with the omni-directional rollers, but the wheel treads came off after about 2 years. These are made of rubber (vs. plastic) and magnetize into certain directions, which is a really neat feature. Overall build quality is solid and they have plenty of zippers and places to put your stuff. The included garment bag was weird at first but I've grown to quite like it. Now that I'm an adult, I guess I wear dress shirts, so it's nice to not have them super wrinkled when I arrive at my destination.
Cons: A bit small, but that's to be expected for a carry-on. However, it could have been bigger if they made the wheels a bit smaller. Nevertheless, I think they made the right choice as the wheels seem more durable and will probably last longer. Another con is that if you pack the suitcase too much then the handle will sometimes not come out because the suitcase is bent a bit. I had this problem with my last luggage. I'm a bit disappointed because I feel like this could be avoided with better materials. However, maybe they decided to optimize for weight, who knows.
Impression: Overall, this is an excellent suitcase that is backed by an unbeatable warranty. I will almost certainly be buying one of their larger sizes for future longer trips.
