I'm not sure about it either. But after trading some messages and looking at the poster's selling history, I came to the conclusion that he did not know the extent of the damage. The ERA, especially this one, has tight fitting o-rings, I can see how someone would think the cap was threaded on instead of the double o-ring fit. Clamping down on it with a pair of pliers/vise-grips was not smart, but hey we've all done stuff like that...
The included ERA fits on the VVG solidly. If I hadn't tried a number of different devices I would've never known there was a problem.
Rob should have my VVG sometime on Monday. When he gets thru the reomizer2 launch and other stuff he is working on I'm sure he'll get me fixed up (he better charge me for it or he is crazy). That's one of the reasons I'm such a Reo fanboy. I have enough equipment I'm not worried about a new toy I bought. I was holding out for the super-secret P68, or whatever, but I couldn't resist.
Did I get burned? Yes. Was it intentional? I don't know. I'm going to give the seller the benefit of the doubt. To do otherwise would make me angry and that serves no purpose to me.
I have grown leery of the classifieds though. Too many inexperienced jerks trading their ridiculous priced mods has ruined what was once a good thing.
