I have had mine for 3 years and am as happy with it as I was on day 1 everytime I look at the bottom of my rig and see how clean it is. :

It is a bit pricey but the benefits outweighed the cost for me. Especially since the vacuum pump seal was starting to weap and after installing the airsep has stopped that was 50k miles ago. The only issue I had was the custom oil fill cap started leaking under hard trailer pulling days, I called them and since I ran an aftermarket turbo with more boost they custom made another to compensate for the extra boost pressure. No problems since. There are pics in my readers rigs.
