Wheels are useless

This is an attractive, elegant case but the wheel design is AWFUL. Unlike those on rival products, the spinner wheels simply do not work. It's impossible to pull this bag behind you. On hard and carpeted surfaces, the wheels often refuse to align with the direction of travel and, instead, skid along sideways. After dragging this thing 1/4 mile on pavement, I was exhausted and one of the wheel housings was worn away. If you try pushing it on all four wheels, the wheels catch every surface irregularity and the bag wanders. Like another reviewer said, this thing has a mind of its own ... a very sick mind. What a shame! The rest of the design is really nice but what use is a wheeled bag that doesn't wheel?
