As a Flight Attendant and an avid supporter of Samsonite hardcases for the last 20 years, this is not their best thought out design.  I bought it with considerations for terrain outside of airports (bigger wheels so they don't get gnarled up in the snow and grit) and just assumed the rest was tried and tested by Samsonite.  The rest being..ability to get to the airport, by train or bus.  This (31") is not designed to be manouvered in any way other than its upright pulling position, it does not fit down the aisles of buses, cannot be manouvered easily through restricting barrier entrances to trains/airports, it's back breaking and not condusive to manual handling due to twisting and lifting at the same time.  There is only one handle to do any lifting of the luggage, putting all weight on one side of the body.
So, Samsonite, it could do with another handle on the side for lifting, and the ability to swivel so it can fit through slimmer spaces than its full width, the rest of the case is just as I would expect of Samsonite's high standards, hard wearing, durable, light as can be and no frills.
