Venturi vacuum pump

I'm sorry that you don't like what I posted, I made no personal attack towards you nor did I say anything negative about the product you have made. I merely shined some light on a product that does something similar to the thing you designed, but goes about it in a different manner. I did not make any false claims and after re-reading what I posted I do not see anything that does not make sense. It seems like you are getting very defensive for no good reason and frankly I do not understand why.
