For the money a good pick. It has the same output of the 9P that has been discussed here lately. The form and finish (I strongly prefer HAIII) have been improved, although soome don't care for the clip, I like it.
Personally I like the C3, I have two of them as well as a M3. Although the M3 does have a slightly greater throw and output is it worth twice as much?
If I could only buy one incandescent it would be the M3. However, If I had any thought of buying a M6 in the future I would buy the C3 and apply money saved towards the M6. The M6 kicks butt and is the light that can signal satelites from space.

OK, I know someone here said don't be impressed with that factoid, but sorry it does impress me!
