My girlfriend talked me into one for my main luggage. It's "okay" but
honestly I'd switch it for a two-wheeler in a second because I find it
difficult to control.

What's funny is that shopping carts in the UK suffer from the same problem.
Unlike the US carts with fixed rear wheels, the UK carts swivel on all four
wheels. I find those very hard to control as well.

The reason people buy four wheel luggage is the cheap two wheel cases
where the wheels are too close together. These are unstable and tend
to tip over.

Cheap four wheel cases don't tip over...
