A microfactory that found success with its nugget ice maker has now turned its attention to ice for frozen drinks. The $399 Opal ($67.97 at Amazon Marketplace) Flake Ice Maker from FirstBuild is a countertop appliance that whips up to 36 pounds a day of especially soft ice that's suitable for slushies, snow cones and frozen cocktails. 

FirstBuild is offering a limited number of machines for preorder now. According to the product's website, you should expect to get your hands on the Opal Flake within six to eight weeks after ordering. 

The Opal Flake Ice Maker is supposed to remedy the frustration of making this sort of ice. The traditional method is to manually shave down ice blocks with brute force -- a typical technique of street vendors. The other option is to buy an expensive commercial appliance. Sure, you could chuck regular ice cubes into a blender and flip the switch, but the result is often tiny bits of rock-hard ice.
