I'm just now unboxing mine, and it does the same thing. Small bummer I guess, you get this nice USB cable, then plug it in and it wobbles up, down, sideways, and every which way but loose. Attempting to unplug it pulls the entire female connector forward until it stops on something, then you can remove the cable. I'm still waiting on batteries for mine as well, and if this is the intended design I guess it will function fine. That said it doesn't exactly ooze feelings of quality...
Mine also has a very slightly misaligned top plate, similar to what Phil Busardo pointed out in his review. It overhangs very slightly on the fire button side.
Finally a question for the owners here. Both of the brass battery caps on mine are scratched up, one pretty heavily, right out of the box. And mine has a small scratch (Maybe 5mm long) through the anodizing on the bottom next to the left battery cover, directly left of the bottom engraving.
Obviously minor cosmetic issues are going to happen to any mod as it's used, which I totally get. But it kind of sucks to get what to me is a very expensive mod (I had to pay tax and shipping on mine, so I probably have the world's most expensive VF), only to feel a little like I got a used (Or "Demo") device right out of the box. I can't see any evidence of an atty having been mounted on the 510, but I've spent all of 10 minutes going over the device to this point.
I'm going to talk with the seller tomorrow and see what he says. I've been fascinated by this mod since I saw it, and the overall design of it is brilliant. I feel very lucky to be able to have it, but the little QC issues (Wherever and however they were caused) have definitely sucked some of the excitement out of this purchase for me.
Comments from owners on any cosmetic issues you noticed out of the box would be very helpful if anyone cares to share. Part of me is saying quit being picky, use the flask and enjoy it. The other is saying I just bought a hella pricey mod that I'm going to be using mostly at home and taking steps to keep nice, and it's OK to expect it to feel solid and look new as it's pulled from the package.
Cheers all!
