Review title: Doesn't work
Product review: This product worked for about a week, then I noticed that my dog was not reacting to it anymore. Humans cannot hear the noise it makes, so the only way for me to test it is to wait for when my dog isn't doing anything and push the button. Nothing. The flash light works so it's not the batteries, it just doesn't work anymore. Spend the money for a more expensive trainer.
