Product review (5 stars): One of my best purchases in a long time! Super happy!
This is the first review I've ever written during my years of buying on Amazon. I just HAD to say a few words about these liners, as I think they are among the best things I've ever bought. Previously, I had only heard about Silpat, but none of the Silpat mats would have fit my cookie sheets (I guess I don't have the "standard" size). I read that the Silpat mats could not be cut due to the inner fiberglass content. So I looked for something that could be cut to fit and I found these. I was concerned that they were called oven liners, as I wanted to actually bake on them. But it sounded like they could be used for baking also.

What spurred me on to looking for these was after I tried a new recipe for oatmeal cookies. Even though I used vegetable spray on my cookie sheets, the cookies stuck - not just a little - I had to chip the cookies off the sheets, hammer and chisel style! The next batches of these cookies I used parchment paper, which worked great, but I'm too lazy and cheap to keep cutting and throwing away the used parchment paper. I would reuse the paper for several batches, but they got to be kind of gross after a while.

After cutting these (easily done with a pair of scissors) to fit two large cookie sheets and one small one (with one more uncut sheet to spare), I have made several batches of the oatmeal and other kinds of cookies, including sticky meringue coconut chocolate chip cookies, and NOTHING has stuck to them!. My cookie sheets have not touched water since I've started using them. I've also roasted vegetables on them.

Cleaning the mats is a breeze. I wash them by hand in a dishpan of soapy water and the greasy residue comes right off. I am so happy with these liners, I will (unfortunately for my waistline) be making more cookies than in the past. The worst part about making cookies before was cleaning the cookie sheets! Not any more!
