Product review (5 stars): Stove Top Extender
I was pleased with them they fit great where I needed them.  So far nothing has melted they are working just fine.  I do bump them & they slide little forward but all I do is slide it back.  They really do stop things from going down the side of my stove.  I would recommend them to purchase especially when you have pulled your old stove out & seen all the grease & food that has dripped down the side this has stopped that from happening on mine.
