i had a cat 1 alarm and imob fitted last year, its a meta. i have had no problem with it at all, never gone off when it shouldnt have! cost me 350 and it opens the doors on the key fob.(i had to have central locking motors fitted buy yours should have that already) most insurance companys want cat 1 alarms as they are approved (toad and clifford are also top bits of kit)
Also alot depends on how good the person is who is fitting the alarm, as they set up the basic settings of the alarm, if they do things wrong you can get fauls alarms and other stuff, just because you get a certificate doesnt mean you get a good job, shop around and pick a good installer!ÂÂÂ
