I bought one last year. I laughed, I cried, I kissed 60 bucks goodbye.
It sucked donkey butt.
It really needs a #$load of CFMS to drive it. It also needs inline dryers to keep moisture out of the thing.
Want to come by and pick mine up for free?
I think if I hooked another air compressor in tandem with my first compressor, it might work. I can't blame it since I am the one without the CFMS, but it did not help with my project whatsoever!
If I had to do it again, I would buy something like this:

Edit- reading widebody's comments, I had similar problems with the nozzle, and when I was messing with it, had the thought "This would probably work well if I replaced everything on it"- and had to laugh because that's essentially what he wrote!
