Review title: Junk
Product review: There are 2 problems with this unit. The first is that there is no on/off switch requiring you to remove the battery to turn it off. The 2nd problem is that it uses batteries very quickly even when the dogs are not barking - you will be lucky to get 72 hours on a battery. This is not a fluke, as I have 2 units & both do the same. I have discarded both of them.
