Zen,
I know this is all very personal for you, but I hope you don't take these things so hard. These types of things are bound to happen no matter how much time and research you put in.
The way most have dealt with devices in the past is to get them, play around and then come up with solutions to problems we might have. We all have some knowledge of pv.s and because of that will often be quick to come up with our own solutions to perceived issues (ie, the o-ring adjustments that were made). It is not personal.
I am guessing this type of pv is also new to some people, so some of us did not know what to expect. Because it came prepared already, I'm guessing most people thought they would be rearing to go straight out of the box.
This will all settle down as we figure out to use these properly, and then settle down further as you deal with the inevitable small issues that will come up with a brand new device.
Last but not least, please go to bed as I can see you still floating around here. You have to work early tomorrow
