Is it a pain to take on and off when you drive?
Not at all. Less than 30 seconds to slip on and lock and viceversa to take off.
I just toss on the passenger floor or back seat when I'm driving.
The only pain is to reach over to get it when I'm going to slip it on.
When I use to park in my garage (can't now the Jeep is too tall) I would put it on. Find a distributor near you, take a look at it you won't be disappointed.
I like this one better than the CarGard becuase it also locks your steering wheel. If they happen to get it started they can't get a full turn out of the steering wheel as opposed the the CarGard brand.
I've had both got rid of the CarGard for the Lok-Itt. The Lok-Itt is made of thicker steel.
