I feel the need to ask... does your bottom cap screw in completely using AW IMR's? There's no way I can, spring is way too stiff (sometimes I can even hear it like "click" on the inside). I can force it to mount almost flush (~1mm gap), but my batteries get scratched. Another problem I've found, judging by touch, I believe there is no reverse polarity protection at all, the pin that touches the positive exceeds from the delrin. Not willing to try at all...
Also, I can see some machining issues here and there, quarter of a circle scratches where the box that holds the dna makes a corner with the tube halfway to the corner where the LCD is at both sides, some irregularities in the cutting of that piece, and a thick line in the switch just where it bends (this last one I found is quite normal, but it's there). Plus, the battery tube doesn't sit completely flush at the top, it stands out by almost 1mm at the opposite side of the screen.
It's not likes it's crap or subpar quality, all in all it's an amazing PV, I just believe it's a way too complicated device to make, and quality control hasn't been as high as I'd expected watching Mike's interviews and so on (hype is way too bad, this has happened before to Imeo fans, and it's happened to me now with Zen). Anyway I wanted to know if any of you has seen this kind of things or if mine's a lemon or sth.
I'll try to post pics tomorrow of the issues I've described. BTW, new batteries, with around 20 cycles, and the DNA30 always says weak battery. They are the real deal, they're from an official AW distributor, I don't know why it just keeps on saying weak battery always (JUST when it starts up, then it fires without a hassle). DNA20 does the same thing though so...as long as it keeps on firing, I'm not too worried.
BTW: Being fair with this device despite what I've said, construction is top notch, the concept is really close to perfect except for the 510 connector, and the buttons, specially the firing one is, simply put, just the best I've ever seen in a VV/VW device by far. It's the only VW mod I've been able to use with gloves!
