@Tahoewhat, when I received my alarm, it had a bad contact to the selenoid or something like that. So I contacted the company and they gave me instructions on getting another unit. Even though they say refurb, I believe that most are brand new and they are just moving them to make room for the 2010 models.
Other than that I'm very impressed with the system and the two way remote will wake u up if it's going off. Other than that does anyone know how to turn the volume up on the siren? It's seems as though my horn is lounder then it right now. But to me for the price you can't beat it.
