imo, clifford is really good. i had it installed in my car and it has never failed me. astig pa. drawback is mahal nga. they have different models but there's the one that talks, intellivoice yata, that's really catches everyone's attention. the voice is not robotic like the vipers. the switch is not the toggle kind that any1 can disarm if found, it's like a pin code system like the atms. if i'm not mistaken i saw someone selling the same alarm in bidshot.com yata for more than half the orig price. hope this helps :D
