Pretty cool that an 8.5 year old thread was revitalized!! :good2: :laugh:\n\n\nI had a Mighty Mule magnetic driveway alarm that was a piece of crap.\n\nMy Harbor Freight alarms were triggered by shadows. \n\nI've had good luck from my Dakota Alerts! I've got the shorter range system (1000' I think) and it works fine several hundred feet from the house, even with the receiver in my basement office.\n\nI've also read good things on another forum about the Guardline systems. They supposedly have great customer service.
