This alarm works well on my Dodge Durango and I have had it for over 2 years. This is one of the best high-tech alarm system I have ever came across. It has its kinks like when the alarm goes off, it is hard to disalarm so I just take the batteries out. Other than that, it protects my truck. Five vehicles on our block was broken into and based on my neighbor's camera, this person was looking in my truck for quite sometime before deciding to break my other neighbors Nissan Maxima window and stole valuable out of it. This alarm system would have gave me notice as soon as the assailant would had attempted to break into my truck. I love it and I will not replace for any other alarm system and lets not forget, it has an automatic starter, which is needed for our winter months here in Philly.
