Are Anti-Theft devices any good?
Some are great and some are not so good. The fact is, most serve as a good deterrent. The idea is to make your car a less desirable target than the car next to it. If you have two cars sitting side by side and one has some theft deterrent device on it and the other doesn’t, what car is the thief going for? Most likely the one without the theft deterrent device on it because it’s safer for the thief.
