Jetbeam RRT-0 with an AA extender seems pretty bad ***...any other contenders. I should have mentioned that price is not my main concern, performance is! Are there any 1xAA lights that can compete with this one that are no bigger? If not I'll have to order one of these too.
It is very nice except I hate the tail switch. It feels so spongey and requires quite a deep push to activate the switch. Considering the switch is recessed in the tail cap, it does make it a chore to switch on the light. If you don't need the strobe feature, go for Sunwayman V10R. I bought the Ti version and I love it. There's an AA extender for the Ti version too but I don't see a need for it. If I got to be carrying an AA extender for emergency in case my CR123 runs out of juice, why then can't I carry extra battery instead? The engineering quality of the Sunwayman felt better too.
