Oddi in the South we call that "funk" buildup...
edavis, we've got one eGo that's a bit quirky on a thread up, and won't work with one larger beauty collar, but we've got a dozen or so of various mAh eGo's and they work great...
if it was that way from the beginning I'd try for a return/exchange
I got the 2200 mah eGo Mega battery in yesterday works great with all the pro tanks but I wanted something to fire up that humongo Nautilus tank Ive got and it won't work with it
