Title: Does not live up to billing
Review: We have had this device for over a week. On the ultrasonic setting can not tell whether or not it is working. Silent to us and the dogs continue to bark when someone comes to the door. On the audible setting now we have both the barking dogs and this hi pierced shrill when some one comes in the house. the dogs don't bark as long but it goes off for the slightest of loud noises in the house. Next option is to try a shock collar but I think I will get resistance from my daughters
