I stumbled across this device and thought "hmmm I thought Todd had the patent on this. Then again maybe not or maybe its not a violation of patent laws. Anyway, anyone every used one? Seems like it needs more holes to be efficient like the AMPS. Price has the AMPS beat by a bunch, I saw this device for $11.99 but I like to support those who support me. And Todd has helped me on a couple of forum topics so I'll stick with his stuff!
