Query: Save your money, buy a slingshot - you'll have better luck scaring away pests with that!

I bought a few of these units to scare away racoons from my pond. They suck! The racoons are laughing at me for wasting my hard earned cash! I wish I would have spent the money on beer so I could at least be drunk when the racoons are killling my exspensive Koi!
