Review on Ultrasonic Animal Deterrent with Solar Power and Motion Sensor - Effective for Cats, Dogs, Foxes, Birds and More by Nicole Brand

This product worked great until it failed. It's supposed to be weather resistant, but it doesn't work in sub-zero temperatures (it's cold here, maybe 40 seconds). Turned on and off after moderate rainy days. After a month the sensor was working sporadically and you could hear that the speaker wasn't working well because the sound was different from the first reception everywhere. The light was supposed to blink and after two weeks it stopped working constantly. Started well but didn't last. Maybe others will have a better experience if the weather doesn't change. The item has been returned for a refund.
