Product Test: We had some help from viewer, Nance to test out the StufZ Burger Stuffer. It is pretty easy to use. You just put the beef in, add your toppings, more beef on top and push it all together in the StufZ holder. In the end, you have a huge burger stuffed with your favorite toppings. It cooked up nicely. Our tester said she could probably do it by hand and not have to clean the product or stuff it in a drawer somewhere. Still, worthy of thumbs up.
