Not bad at all – UltraFire C3 2xAA Extension Tube Reviews

Involvement:Expert (understands the inner workings) - Ownership:1 day to 1 week

Gives something like 4 hours runtime from 2 AA rechargeables. Still quite small for a 2AA light.
Threaded portion at tailcap end not long enough, the extension doesn't screw in enough to make contact with the tailcap. A small loop of copper wire will fix this.
Makes for a small and light 2AA light - needs fiddling with to make it work though.
Useful - but I prefer the 1AA size for this light.
