Has anyone got these? If so, have you experienced any problems with it randomly going off? Mine did it a while ago and I took it back to the dealer and he said I needed the sensitivity turned down. Had that done then it did it again. He then told me that the moisture in the air can set it off!!! If I wanted a weather forecaster as I car alarm I would have kidnapped john kettley or michael fish and put them in my bot with a machete!!! Anyone suffered this problem?
