I have a RF425 installed on my Getz. So far, I have no negative inputs from the unit itself aside from the actuator they installed. I had two(2) busted actuators replaced already in a span of 8-10months. The first one was busted on the first month upon installation. The replaced actuator got busted around end of October. BlueLazer replaced the first one, but as for the second one, I opt not to go back because of the distance since I reside in Antipolo. I had it replaced by another auto shop instead. Aside from the busted actuators, the alarm unit is a good buy!
