Ion (I could put all the blah-blah of every last custom bolt I have put on it, but let's be honest - that is really only to make myself feel cool and really has no impact on this product)
Easy to Install
Keeps pin of air tank pressed in for too long
Have no opinion on NDZ, so I feel I am being pretty objective.
Decided to address the nasty duckbill on my Ion. Didn't want a full drop so the guy at the store said, "How about this?"
Brought it home, put it on. Hooked everything up. Turned it all the way Off, screwed in the tank and started turning it On. All the sudden, it is like I have burst something. I turn it Off, check all my seals. Everything is alright. Turn it back on. Again, it is exhausting like there is no tomorrow. Investigating, I see it is coming out of the bleed hole.
I monkey with it for over an hour to no avail. Anytime I turn it on or off, I have a good five or six turns of the knob where it is neither on or off and it is just completely empyting my tank.
Take it back to the store. Guy says it definately should not be doing that. He monkeys with it to no avail. Let's me swap it out for another one.
Take it home, same result. Alrigh, maybe my tank is hokey. Try another. Same result.
Now, I want to be clear, this is not a quick "Psst!" bleed. This is a just gushing out for several seconds and several hundred PSI while I frantically try to get the knob completely off or on.
I know this company has a good rep. I also know that while I have been playing a long time, I am not the most technically inclined. Giving them the benefit of the doubt and giving this a three to keep the overall scale on this product fair. Although, personally I am taking this back and saying "Give me ANYTHING else, including my atrocious stock duckbill".
I've had the same thing. The problem is that the tank screws in too much.
What happens then while you're screwing in the knob, it starts pressing in the tank valve too soon, releasing air, but the o-ring on the on/off brass rod hasn't travelled enough to seal yet, hence the huge volumes of air escaping through the front (closest to the knob) bleed hole.
I threw a metal washer into the asa (2.5mm thick, 16mm outside diameter, 8mm inside diameter) and now the tank screws just that 2.5mm less and I have absolutely no problems at all.
Busy looking for a better on/off because a washer inside is not ideal, but it solves the problem for now.
