Query: Great idea-bad implementation+safety hazzard-Save your money

Completely unsafe. Spewed large amount of burnt plastic smoke, rickety clamps to hold on plates, steamed, did not "fry" hamburger. Took twice as long as book said to cook, took 3 times as long as the smaller GF grills do. Plastic top too hot to touch even 10 minutes after it was unplugged. Did I mention it smelled like burning plastic for the entire time it was on?
