Aside from the obvious, being that they are used indoors, these grills are much safer than what you're used to. The smoke can be quite dangerous to your health, and there is an inherent risk when operating traditional grills with the fire and the splashes of oil that can fall on your skin. Moreover, they offer a compact solution to the constant problem of the lack of space for grilling in your backyard. By purchasing a product such as the Cuisinart GR-4NP1 Griddler, you'll never have to worry about that.
