Does not work well
I purchased this last winter and during the cold weather tried using it in an unheated garage.  The results were underwhelming and I believed that it was the cold temperature, which definitely was a contributing factor.  However once the warm weather got here I tried it again, followed the directions and the results were disappointing.  There is a lot of work that you must go through and there was still a lot of carbon left on the range burner grate.
