I bought a brand new Argus Pro and when I got it the box was sealed and unopened, I pulled it out of the box and the air adjuster fell out and is gone, can't find it, and do not know it's a threaded hole or if it's pressed in, didn't last long enough to pull it out of the box and now I got to find something small enough to fit the tiny hole, and do not think they sell a replacement lever
