Most qevs are the same like the virtue and ND are basically the same thing. Qevs are sopposed to save air and increase rof. And the ND qev does just that. All you have to do is cut the hose about an eighth of an inch and screw it in until sevure, if u over tighten it, duh its going to leak
but u have to be a complete idiot to do this, it says on the box it comes in "do not overtighten".
The ND qev is a qev plain and simple i recommend it
