+1 for the "WF" from dealXI am carrying a Surefire E2E with dealextreme (china direct) CR123 Batteries right now. I have not done a side-by-side with my surefire branded batts. But these seem okay to me.
For the price, and with DE having free shipping (from CHINA!!!), what's so bad about buying some and trying them out and seeing for yourself? That's what I decided to do.
never had a problem with em.
