It seems to me that a system like this requires more space and weight than a gearbox that's just designed to have X number of stages to begin with. Something like this could be great for prototyping - you have a bunch of stages sitting on a shelf and start putting them together until you find the ratio that works best - but that's as far as I would use it. Once you know what your application needs, buy a gearbox with that ratio. The weight savings can always help, and the space savings may be a significant difference in some robot designs.

To echo what has already been said, I think the main issue is that all they were good for is prototyping; for actual competition use they're a solution in search of a problem.
