Work pretty well

These works pretty well although they are not perfect. The first thing I will mention is that you have to pull the pieces off of the middle of each burner all the way to fit these on properly. Otherwise they are too close to the burner. These have to be cut down to customize to your stovetop so they aren't really a perfect fit. They are really easy to cut though. I wish they fit so that they covered the sides of the burner too but I have a really old stove with lips so they dont cover that. All in all, these are cheap to buy and easy to use and I would say they work relatively well for their intended purpose.
