Product review (5 stars): These non stick mats are a keeper!
Boy I'm glad that I purchased these oven liners.  They will come in quite handy.  I received these oven liners just 2 days after I ordered them.  I placed one of the liners on the bottom rack in the oven yesterday.  I made a Hatch green chili chicken enchilada casserole that was just loaded with sauce and cheese.  This liner made the cleanup so easy.  I was able to pull it off of the rack and wash it quickly by hand and back in the oven it went.  No more awkward cleanup jobs for me.  This is a keeper!
