Review on 🐶 TIFTAF Bark Collar - Safe and Humane Anti Barking Control Device to Train Your Pet. Suitable for Large, Medium, and Small Dogs. Rechargeable, Rainproof, and Lightweight by Holly Bell

Arrived quickly after ordering. I love this bark collar. Has 3 settings. Audible (beep) vibration and shock. There are 7 sensitivity settings (from 1 to 7). You can install only one of the 3 options, install two or all three options. You can adjust the sensitivity for each option selected, or set it to 0 (zero) if you don't want to enable that option. I have 2 dogs in these collars. I didn't even have to set the shock option. I set the volume to 5 and the vibration to 3. Sometimes I don't even turn them on and most of the time they don't bark anyway. I've only been using these collars for 1-2 weeks. They are charged with a USB cable (one included). It even comes with a collar tester to make sure it's working. The instructions are easy to understand. So happy with this product and would highly recommend.
