The humidity and heat in our area often makes, otherwise, cooking and baking tasks considerably more challenging. Rolled cookies and pastries, especially, require a fair amount of trial and error and finesse to get it right. I'm so happy that I stumbled across this product. It's a great product and a good value. I enjoy the ease with which the mat and guides allow for consistent rolling of dough and pastry. I use parchment on both sides so that whatever I roll out can be easily transferred to baking sheets for chilling. The mat and guides keeps everything contained and consistent and cleanup is effortless. I like the 1/4-inch guides best and appreciate that there are 4 of those. I'd like to have 4, rather than just 2, of the 1/8-inch guides. It would be nice, as well, to have an option to purchase additional guides in other thicknesses.
