Failed

This product worked for like the first month. I was proud of the results. Then, it stopped working. My dog figured out it stopped working and stated to bark all the time. I changed the batteries and still didn't control my dogs barking. Didn't work when she barked. Every now and then it would beep when she shook her head. But stopped working when she barked. For the cost of this product, I was hopping for a better product. Now I have a useless collar which barely does anything. And on top of that, replacement batteries are hard to find. You have to speacial order them online. Which delays the time of this product.
