V1 for me, works flawlessly has saved me numerous times.

 

No, not really. Head placement is critical. Without doing something that would be painfully obvious it would be difficult. I take my V1 from car to car. The laser jammer on the other hand is too involved to move. You're better off just bringing your V1 along and being a little more careful.

 

That's what I figured DeputyDog. I do take my V1 on my business trips but I am running into more and more Laser guns.
