I'm disappointed with the product and wouldn't recommend

I have only used this product twice since I got it about a month ago. When I came home today, it was constantly making a noise. I would expect it to do its job (which I'm assuming it did) but not when my dog isn't barking. I took out the battery to see if it would reset itself but when I reinserted the battery it kept making the same noise. I'm disappointed with the product and wouldn't recommend.
