Omg, _nderscore, I can't thank you enough! I just got one from sun-vapers for about 5 bucks. This one gave me some serious pain trying to get the center pin out, had to scare it with a hammer. Couldn't get the insulator out, so I dremelled a groove into it in place and ground down the center pin so it wouldn't stick out so much as to short the 510 connector.
This actually seems to work better than the original ERA! Since the juice is coming up straight from the bottom rather than from the middle of a post, it's flood proof! Any excess liquid gets sucked down into the bottle. No flooding, no leaking.
All that for 5 bucks and half an hour of fiddling! Well, fiddling is free, since I actually enjoy it.
Thank you again!
