No problems with order or delivery. The sensor unit didn't work well in low sensitivity mode even though passing cars were only 5ft away. Had to set it to sensitive settings for it to respond. but that was the least of the problems. The main problem is that even at maximum volume, the receiver isn't loud enough to be heard. If other noises are heard in the house (e.g. the sound of a TV or radio in another room), the person must be in the same room where there are no other noises in the house to hear the alarm.
