I've used the non-stair-climbing version (just two wheels). It worked well, but had to wrap bungee cords around my keyboard amp to secure it to the band truck frame, otherwise it would slide around and become unbalanced. But it works pretty well in general and mine is probably about 10 years old now.

There have been many times I wish mine could negotiate stairs better. I may have to look into one of these myself.
