4.0 out of 5 stars Great Product but can be noisy......, November 17, 2010

First let me say that the product itself works wonderfully. I had mine installed in A pillars. The problem is that they remain active even after vehicle is started (This is because vehicle alarm stays active when remote started). The result is a signal to the brain which causes internal relays in brain to click. Starts to drive you batty after a while. Thus depending on your brain location, can get real annoying.

Is an excellent product, without problem it is being added to my Viper alarm, easy installation, no problems adding more items with it, be sure to put in a good point inside the car, is more effective if you put from middle to up.
