One of the reviews says "It quietly rotates a few inches every hour or so." I think youd want at least 1 rotation / day, Id think 4 complete rotations / day would be about ideal tho. Anyone know if there is something else similar to this available at a reasonable cost, that would hold more weight, maybe up to 100lbs? Its cheap enough at least, maybe someone could buy one and give it a go and see how it works....
