Product review (5 stars): Love them!
Solved my problem of dirty drip rings around my burners. Wish I had found them sooner. Unless you are a very messy cook they will work for you and when they do get dirty, you just toss them! I used to scrub my catchers and line them with foil about twice a year. What a pain to do, these make the job a snap. I will always use them on my stoves from now on.
