I have been carrying my CMG Ultra for years. The other day I thought I had lost it. Even though I found it, I figured there must be a newer, better, small, LED flashlight made since the CMG. I thought about the Ultrafire C3 with the extension tube bundle. Then I read here that the build quality has gotten so poor that they are no longer worth considering. Is there a solid performer, tough, single LED light for about the same $$ as the C3? Whatever it is, it will be in my pocket every day. I will only be using standard AA alkalines. I'm never without a light and a pocket knife. My CMG has come in handy more times than I can count.
