I was thinking about getting one of these (http://www.frostfighter.com/prt2600.htm) for my 71 cutlass as I use it as a daily driver, and live in an area where ice and snow are an issue sometimes in the winter.

Has anyone installed/used one of these kits? What do you think of it? It is not really very expensive so I think I am going to give it a shot, but I would love some feedback before I spend the bread.
