Review on 🐶 UltPeak Dog Barking Control: USB Rechargeable Sonic Barking Silencer - 10 Meters Effective Range, Safe for Small, Medium, and Large Dogs by Hesham Peltier

I have purchased 2 units and both have been effective in reducing the incessant barking of neighbor dogs from 15 to 30 feet away. That was true as long as we had clear skies. When it started raining, one of the blocks turned into a bottle filled with rainwater. I disassembled it, dried it and charged it, but I'm not sure if it will work again. The other block continues to work as expected. Another issue is the bright red or blue lights that are on the front and visible to the owner of a barking dog across the street. This light should be placed at the back where it is less visible.
