Well, after about 2 weeks my neighbors obnoxious pit bull is about 80% quieter. And, I do like the remote control. Giving him a big long dose of noise usually quiets him and he goes back to the other side of his yard. In fact, I noticed that he no longer spends much time on my side of his yard. It’s mounted on a palm tree about 10′ up looking down at the neighbor’s yard. So far it’s been well worth the cost.
