Work nicely.

These are great if you live in any cold weather climate areas and want something to warm yer bum if you dont already have heated seats. I put these on undera seat cover using the 3 sets of latches. I then covered the seat with my seat cover. They are slightly padded and add a little comfort. There is a low and high setting as well as off. Connects to you cigarette lighter outlet. They do have a strange odor out of the package so I left them out to air out a few days in the garage.
