admittedly i dont install / maintain that many compared to some of you, but of all those i have installed ive never had any problems or been called back to any faults with them. maybe im just lucky, which is rare for me. as much as id rather install a monitored alarm for someone, not everyone wants one and sometimes its a basic dialler that gets fitted. or bells only
customers may not always have an idea what they want but id rather give them choices rather than telling what they are having
