Review on Awaiymi Upgraded Rechargeable Vibration Reflective by Abby Clark

Bought a pair for my two Havana cats when we moved to an apartment where other pets and people were closer to our glass doors and windows. It was also necessary to walk them at all breaks. At level 1, they learned very quickly not to bark after the initial vibration and beeping. The battery lasted two weeks because you didn't have to warn them. You can grr and growl at low levels without getting annoyed. It doesn't have a shock function, which I think is more humane. One caveat: when I took care of them, they were initially afraid of the noise and vibration of the razor, which was like a collar. You knew the difference. 12# dogs collars are lightweight and adjustable.
