This is a fantastic piece of design. I really like this rubber cover since it serves the purpose of preventing insects and dirt particles from accumulating onto the surface of your greased griddle while it is not being used. I also purchased one for my home griddle that I use throughout the summer. Before you put it on, make sure that the surface of your griddle is well cleaned, oiled, and completely cooled. Also, make sure that you remove it before you start using your griddle. On this, you should NOT be cooking.
