That was what I was thinking.
Installed it, not as powerful as I expected. The rotating head doesn't swing around as nicely in this demonstration, so I figure I will just use it as a standard PH. I've removed the clear rotating head on the end. Turns out to be around the same price as a normal PH. But this one does come with a 3 year warranty.
Will get some pics up shortly
