This grill is smaller than I thought it would be in person, and it's essentially a non stick skillet. I can see the appeal of it for making certain foods that require a completely flat surface, but to me it doesn't add much value to my kitchen appliances since it doesn't add a nice "grilled" flavor that comes from charcoal. 
All of that said, I do think it's a useful appliance for when you need to make certain foods on high heat and a regular skillet might not work. It also works well as a panini maker.
