electric supercharger?

my friend found this "electronic supercharger" on ebay for $30...heres the link http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=2457618698&category=33741 ...is this for real? do they screw up ur engine? and why are they so cheap? thanks for ur help guys...tryin to save my friend some car trouble.

They are so cheap because they are a scam!! DO NOT BUY ONE!!! They don't work and you or your friend will be wasting money. You will see better results mailing money to a complete stranger. :2cents:

Atleast that one looks a little more legit:disappoin . I've heard of the little propellors actually braking off and going in and really messing things up.

i just feel sorry for the poor shmo that bought it:disappoin

well...i dont really want to tell him its crap because hes got an automatic del SLOW that is riced out pretty bad...and hes always talkin about how fast it is and now hes sayin he can be me in my 5spd 95 integra rs...so i think ill just let his car go to waiste
