I use this baking mat already for half a year and I'm absolutely happy with it. The reason for buying was to save me the intention of garbage and avoid disposable baking paper. In the six months I had nothing that would have been sticking to this baking mat. Here you can easily remove probably caramels. Fatigue appears to now no. The size fits almost exactly on my baking tray, which was one of the reasons why I have decided on this mat. Measure Before never hurts here, however. The baking mat is well worth the money in any case and I'll probably even a second to buy myself, because sometimes it takes more than a baking sheet.
Edit 2014: after I had the silicone mat once in the dishwasher and they came out with a plan, I wrote to the manufacturer, since even a 10-year warranty, the mat is promised should withstand the dishwasher according to the product description as well. I got sent to you immediately and without any major problems a new and was allowed to keep the old even.
