Product review (1 stars): "heat resistant" my patootie
My gut told me to keep looking for a metal version of this but i took a chance on the "heat resistant" material it was made of. When my top burner (GE profile) was on it was ok but when the oven is on the material gives off a melting plastic smell which is quite strong. If you use your oven a lot keep looking. This extender is for small gaps (no more than 1/2 an inch.
