Spiral Max

There's a product I've seen an infomercal on a while ago and recently found it on the internet. Can anyone tell me how good it works(if you have one), or if you think it works(if you don't have one).

There homepage is http://www.spiralmax.com/

its crap. The internet is full of scams like this. This one looks even less legit than any other one i have seen. Mainly cause it doesnt say anything about how much PSI is produced or the CFM or how many watts it pulls.
This is also the cheapest one ive ever seen.

All those items like this one are rip offs. Save your $$$
