I think this is a step down from Exact change in a "handful" ways. Size is bulkier. I feel like
you are not left as clean at the end. The gimmick can flash, as it did in the teaching. Doesn't
always work smoothly (can stick). It is noisier, or at least as noisy. Not every number can be
named from 1-100 (even though the ad says a number "up to 100"), but rather only from 50-100. That
is misleading at best. The "move" is a bit awkward and fidgety. Seems cheaply made, and is
technically a couple of steps down from EC. It will work, but I'd go in a different direction for
this type of effect.
