To me the whole idea of an EDC single AAA cell light is something to use to put your key into the lock at night (everyday use), or in more serious circumstances to find your real light (preferably a good headlamp). I EDC a Fenix E01. It has worked well for me. It is plenty sturdy, compact, lightweight, and the price is right.

I frankly don't see that the advantages of this Titan are worth the price, even if it is cheap relative to other Surefire products.
