Title: Can't tell if it works
Review: The collar material is cheap nylon and doesn't hold tight on my dog's neck. After a day or two it needs to be readjusted/tightened. Also, the black box where the inaudible noise comes from is bulky, awkward, and huge! Not cool!I don't think this has been an effective bark deterrent and am glad I also bought a shock collar for the same purpose. That has been entirely more effective. Maybe it isn't working? It's hard to tell because I don't see a way to test it and be able to hear it with human ears. I also cannot tell when the battery is dead. This thing needs improvements.
