Review on PetSafe Outdoor Ultrasonic Bark Control: Effective No Barking Deterrent 🐶 for All Dog Sizes on 1/4 Acre - Weatherproof Bird House Design by Isaac Valdivieso

Doesn't work at all. Our dog actually barks at it. It flashes to confirm it's activated and she just keeps barking. I've tried all 3 settings with no success. The plastic is light but thick enough to last a long time. I would keep it out of the sun. It is very difficult to remove the battery cover. I would probably accidentally break it on one of those occasions. Can't tell how wide the mic and speaker range is, maybe 45⁰ but I'd like 90⁰. I had to buy 2 to cover the full length of my garden (one at each end). NO 4 settings, there are 3 settings and 1 test mode. Be sure to read the instructions and don't leave it on the 1st setting, which is a test mode that may stop barking, but also drains the battery quickly because it's constantly actively "listening" compared to less battery. listening mode. Test mode sounds like a high-pitched, old-fashioned dog whistle, so it can be heard by the human ear to confirm it's working. In settings 1, 2 and 3 set the usage, and the pitch that stops barking and is inaudible: to the human ear it sounds like CB noise cancellation. After 2 months when I had 2 dogs in the yard, my dog barks as usual.
