I have one. They don't work quite as well as a block heater, but they do the job. To do the job right they are best left plugged in all night. I used to use it when I lived in an apartment and the poor beast had to sleep outside in the snow. Now I have a heated garage.  So no plugging in necessary. The whole car is at 60F no matter what it is outside....which currently has been 25-35F  Its supposed to snow in a day or so.....garages are awesome.
