Product review (5 stars): Great for messy cooks!
My mom doesn't see well, and as such, she drops stuff into the eyes on the stove (yes, she's still safe to cook. She drops them when serving). We got these to save the day, and they did! They just pop right in on our Frigidaire cook top. When they get stuff in them, I can usually just rinse it off, but if it's bad, I just toss it into the recycling bin and get a new one. Great idea!
