do any of you guys have these they seem like they would be pretty conveinent but i guess that doesnt matter unlees your really buff or are carrying a bat

 

Got one, I am not buff at all, Im 5'3" but most car thieves dont want to get caught and will take off at the first sign of trouble. It is a very useful device considering that your alarm means nothing if you dont hear it go off. They can also be connexted to radar/prox. sensors so you are alerted before they even attempt to break in.

 

Had one...Works good for door dings/nosey people...

 

What company makes it and where can you get it?

 

works good at night.. after setting it perfect to your type of environment you live in so you know if its a false alarm or not.......... worth it in my opinion. It saved me from possible vandalism many times...
