I had the Mister Burger II for years. It was a gift from my mom for my growing family. We used it until it fell apart at the electrical connection on the machine. By that time it, it had been in constant use for about 15 years. I have a Mister Burger I that belonged to my mom and have used it for years. It's just nice to be able to do 2 burgers etc at a time. Terrific product.
