The gaffs and the routine are basically the same as for hopping halves. There are three problems with the trick. (1) The dominoes are plastic with a matte finish, the nesting is loose, and they don't look real. I sprayed them with high gloss clear acrylic which was a slight visual improvement. (2) The gaffs fit loosely and are noisy, requiring extra care in handling, unlike well-made Hopping Halves where the coins fit with minimal play and noise. (3) The walls of the gaffs are rather thick. In well-machined Hopping Halves unless spectators are extremely vigilant, they are unlikely to notice a size difference in the coins over the course of the routine. Not so with the Hopping Dominoes. During the short time interval between the start and end of the routine, and no matter what common lore says, size does make a difference! If the gaffs were thin-walled and machined to close tolerances, this could be a nice variation of Hopping Halves. Alas, the flaws mean I probably won't be using this set and hence the low rating.

This is a good idea but could have been manufactured better I feel. I will use this item.

Good product
