This is disturbing to hear! I bought two EX11v2's back in October and loved the size of them and beam they throw! Other than the occasional having to unscrew the battery to clear the "confused" state of the light they'd been pretty good with nearly everyday use. They seem pretty well built...
A couple weeks ago one of them started eating up batteries when it wasn't in use -- it'd kill a new CR123 in a day. I emailed NiteCore and they said to return it to the point of purchase for repair / replacement. I sent it in and I'm waiting to get it back. If they've been discontinued I hope I don't have a problem.....
I was actually thinking of picking up a DX11.2 but I think I'll wait on that now. Anyone have any suggestions for a similar light (that hasn't been discontinued)?
