Need help - Found this on Ebay, is the Vortex Generator for real or a scam??

I found this item on Ebay that advertises an increase in fuel efficiency of up to 30%. I'm not a mechanic, but figure if it sounds to good to be true it
usually is. Does anyone have any experience these things, or info if what they say is true? Any info would be appreciated.
Thanks!
John

He calls this one an "Air Razor", and a "Turbinator" in other sales.

Note: "of winning bid". You're still out the original $10 shipping fee, and now you have to pay again to ship it back. Who's going to do that? Nobody, he hopes.
From the ad: "and I will refund your money (minus S&H)" S&H ?? Shipping & Handling? What handling? Ah, wanna bet he charges a handling fee for returns, you know, for inspecting it to make sure it isn't broken, resealing the box, putting it back on the shelf....

Gotta love those non-specific can't-prove-it claims.
From the ad: "This item is NOT Handcut or Home made!" He uses an electric saw to cut it out, not hand shears, and the workshop is in a shed waaaaaay out in the back yard, not in his "Home", so technically the statement is true.

Also the Tornado (which is carried in the Jegs catalog on page 113A, and very likely the JC Whitney catalog.
Thing is, it's not totally false advertising.... it does create a vortex, and just as a hurricane, typhoon, or tornado does, a vortex will compress the air around the eye. If the air is compresses... in essence, isn't that similar to what a supercharger does?
Oh, and there are many models depending on the make and type of vehicle, so you have to make sure you bid on the right one, or it's useless, or so they say.
And if someone is really interested in such a product, the really should check out things like what the retail price is... nothing worse than bidding higher than something can be bought retail, and that does not include S&H.
Might also investigate what real mechanics say... Many years ago, my grandfather, a professional mechanic, used to mix graphite into his oil for his own car. I thought that was nuts. Years later, the oil companies, Mobil for one, came out with graphite oil. What seemed nuts to me turned out to be factual. Of course, now we have synthetic lubes.

What a load of crap. I'm not sure who is more to blame...the crook selling this crap or the idiots that believe putting that restrictive looking cut up beer can in their intake track is going to help airflow.
