I used to really like my ARC-AAA. But then it crapped out on me. Went into a really annoying flicker mode. Replacing battery, cleaning contacts, crimping the head did not work. I gave up on it. My wife managed to drop hers, which should not have been a problem, but somehow the barrel got bent and the head became almost impossible to turn.

I am now EDC'ing a Gerber Tempo single AAA light. It's a bit bigger than the ARC, and had my ARCs continued working I would have liked them better than the Tempo. The Tempo can be operated one-hand whereas the ARCs couldn't be.

I really liked the ARCs. But in my limited experience, they cost too much for what they actually delivered (for me).
