Query: Good product. Not Great.

My wife likes it a lot 'cause she can bbq the meat, steak, fish with a little black burn around the meat. All other machines will automatic turn off when it reaches certain temperature so you can never the burn your bbq with a little black stuff around the meat.But my mom doesn't like that much. That's why I give it a four star only.
