Doreen L. –
We have a mini golden doodle that tends to bark at every mailman, person walking by, and Amazon delivery person that comes to the door. It gets highly annoying. This little unit just stays tucked away under a bench and stops the dog barking without us yelling at it which is pretty helpful. 🙂 The only thing I’m curious about is the battery life. I put a fresh 9 V in it today and we’ll see how long it lasts. I have a currently set on level one out of three levels.
