This purchase was made to replace the ‘tired, over-used’ stove-top mats that we have used on our gas stove for many, many years. The improvements that have been made since our last purchase (possibly 15 or more years ago) are very noticeable, and will give us many more years of stove-top heat distribution. In making this purchase, I also purchased mats for one of my sons, who ‘cooks with gas’ as well, as I’m aware of the benefits gained by using these mats. I couldn’t be without them!!
