I’ve purchased this one[1] and it makes almost perfect cubes of ice that are very clear and melt evenly and slowly. In my cocktail glass it is so flat that the whiskey does not permeate the bottom. The result is a beautifully clear square in the center of my glass when looking at it from above.

Trick is to let the ice temper for a few minutes to acclimate to the room temperature before pouring your drink over it. Otherwise it will crack. Also good to spin it a few times in your glass to melt it a bit to get it perfectly flat.

The margins on that must be incredible. An ice cube tray plus some foam packing material, for $40. Didn't even bother to encase the foam in a blow-molded shell like a cooler.

I would have thought so, and that still could be true, but the knock off brands are nipping at the heels on price. Curious.
