I really like the look of this case, and it felt like a durable enough container. The problem I have is that the body flexes a lot, and there isn't anything sturdy that the wheels rest on. Specifically when you carry another small suitcase on top, the body changes shape a lot, and the tiny wheels catch and scrape on any tiny abberation in the ground (if not tip the whole top heavy suitcase over instantly). But this inconvenience quickly turned into the wheels scraping and destroying themselves after only a few trips. It makes me think that I would rather get a suitcase where each wheel area had those larger double wheels rather than a small enclosed wheel... Though more than anything I want to just go back to a tilting 2 wheeled suitcase that can be counterweighted by a small suitcase dangling off the back.
Long story short, the wheels make for a poor locomotion experience, and will quickly destroy themselves if you expect to use it on anything other than polished marble floors. It might be right for you, but for the majority of people, I would suggest something with more rugged wheels.
