OMG, why did'nt I buy this months ago

HERE'S THE SCOOP ON IT:
A new family moved in next door. They brought with them a german shepard looking dog that they keep in the back yard. This dog barks non-stop all day long, and it's a very deep and violent bark. It boggles the mind how these people next door can be so oblivious to the barking. We couldn't enjoy the inside of our own home due to the barking. Something had to be done immediately. I read the reviews on here which seem to have mixed results. I didn't care if it was going to be a waste of money or not because I had to try something. I bought it and hung it on a tree next to our wooden privacy fence. The instuctions say not to hang it higher than 5ft but we had no choice but to hang it higher. It's hanging on the tree about 7-8ft high and it's pointed down toward the middle of their yard. IT IMMEDIATELY WORKED. We were amazed. It barked once and I guess it heard the noise and it didn't bark for 2 days after that. After about the 3rd day it would give a test bark and then it would quit. We thought it was so funny. Finally relief. However, after 2 weeks the dog started on a rampage of barking non-stop again. We were thinking to ourselves that the dog must be used to it. But after taking it down, we noticed the 9 Volt battery was already dead. I guess we just have to replace the battery every two weeks, but we will. I don't think the 9 Volt lasts very long in the cold.

But, to sum it up, it worked. Also, the dog looks fairly young so I'm sure it's hearing is acute, meaning that it's getting blasted when it barks. HAHA, we win.

The dog next door seems to have adjusted to this bark deterrent, and now barks when he wants to, although he doesn't bark non-stop like he once did before we hung this device in our tree. So it worked for a while and trained the dog a little I guess.
