Maybe think twice before spending this amount

a month ago

So initially I was so excited to be able to afford this for all three of my dogs and not just one. Setting it up and adjusting the fence boundary was a breeze. But as soon as the collar battery started to go dead and I recharged it then It started admitting a warning tone while inside of the boundary. I had to reset the collar. And this has happened basically every time one of them has to be recharged. So beware. I am probably going to go back to my other pet safe wireless containment fence that I had previous I never had any complaints about it.

No, I do not recommend this product.
