i have found the cube to be very useful, however it has it's quirks.
there is one axis where you have a fast forward down tilt of up to 60 degrees (usually set to tilt forward and down. this would be used for a shot pointing down where you don't intend to level the camera base front to rear. fortunately, the cube has a pan axis on it's base to swing the tilted camera around
the other two axes are adjusted with rack and pinion and while accurate and deliberate are slower to adjust, requiring quite a few turns to go 20 degrees. very nice for accurately setting f-b and r-l level; then or course, you have a level panning axis at the top.
also the adjusting knobs are adequate but on the small side
