Review on 🐶 Kozart Ultrasonic Dog Barking Control Device - Anti Barking Deterrent with 3 Frequencies, 16.4 Ft Range, Rechargeable, LED Light, Dog Whistle, and Clicker - Silver by Molly Kaye

The device seems to work, although the sound doesn't seem to have much effect on my dog - flashlight and beep beep are good. I had a billing question with customer service and used the email address on the card that came with the device. They asked me to leave a review. Before I watched, I asked them my question and got no answer. I resent the email for the second time with no response. This was the email address they gave me and advised me to write to them if I had any questions. Too bad they don't answer. I use it (beep and light) but not quite for its intended purpose. But I won't order again.
