This is really easy to use with an easy quick installation of sitting in place on the car seat and place the rubber straps over the seat and then plug in the cigarette lighter and you are ready to use . The seat protector is fed by 12 volt socket cigarette lighter in the car. the colour is black and fit in all cars &vans . I found the lead plenty long enough to use on the passenger as well as the driver side but, this is available with the lead on either side .
