Had this alarm fitted about six months ago. Its been 100% reliable with no false alarms or any other problems like the earlier device that was fitted. I especially like the extreamley bright blue flashing led this really catches the eye and i'm sure its why nobody has tried to break into the Golf. When arming it locks all the doors and closes the windows and suroof, very usefull feature as is the automatic locking and unlocking when turning on/off the ignition. Well worth the money and sooo much better than the clifford I had before which caused so many hassells, the local council kindly ripped it out for me and charged £300 for the priveledge (kept going off all night for no apparent reason). Anyway this is a superb alarm and beautifully fitted by Abacus (no dangley wires anywhere). Highly recomended, Mike.
