We have a compact rig, which means not everything has wheels on it. We can now fit lighting, cable case, mixer and most of our stands on this labor saving device.
Pros:
Good build quality, handles folds down easy with a "pedal" which comes in handy when you realize the last piece you want to fit doesn't really fit...., and it works upright as well.
Cons:
It's a bit on the narrow side, thus the "okay" stability.
PS: comes fully assembled
