Rating : - Don't buy it.
I bought this thinking the price was extremely reasonable and I loved the fact that it had a sound deterrent versus a shock quality. The description they have here is WRONG. It is absolutely audible by humans, so not only do you have the joy of the bark, but the sharp beeping tone is a wonderful addition. You shouldn't be able to falsely advertise like this and I certainly plan on getting a refund.
