I watched the videos and want the hand held one. I even like the wilz wilz wilz sound it makes. I can't afford one and don't do enough cleaning to justify it if I could but BOY what a cool tool. Heck, I'd buy an Iphone if there was an app. It'd beat heck out of a taser or pepper spray. Set your Iphone to de-thug. wiz wiz wiz, thugs GONE! Frosty
