Review on 🔊 Teptec Rechargeable Ultrasonic Dog Barking Control Device - Double Speakers, Strong Waterproof Indoor/Outdoor Anti-Bark Deterrent, Safe for Humans & Dogs by Sara Hunter

Revaing! It works, my neighbor's dogs bark all day. Even barked at night, so loud I couldn't sleep. It really is a nightmare. I want to negotiate with my neighbor but I'm afraid it will turn into a scolding war. I've finally given up! This product has the longest battery life which is why I bought it. After I unscrewed the switch, the dogs stopped barking. I hang it on the door and finally sleep well. Surprisingly, my neighbor thanked me after hearing about it. On the third day one of the dogs started barking again, I asked the seller and they told me to shift three gears. After I put it in second gear it worked again. It also works after noise is detected and the red LED lights up. But I found this sound sensor to be too sensitive, sometimes the audio of a conversation makes it work. Overall I think this is a good product.
