WHOOEE! They are proud of those buggers!<br><br>My first thought on those things would be that it'll likely damage you weather stripping with long term use, seeing as how the velcro goes around the top most edge of the door. Also it's not much of a theft deterrent as is advertized, cut the velcro straps and push it out of the way. A thief doesn't care if they damage the car a little, especially if they're only going for what's inside the vehicle not the vehicle it's self.<br><br>That being said i imagine something of the sort could easily be fashioned, though no more a theft deterrent then that(unless it was permanently welded on), to keep cats and dogs in. I'll brainstorm on it, i know them cats are darn good at tearing through screens >.<<br><br>
