I got a Malkoff Valiant Little Twisty 2xAA and a M31W back in 2011. The M31W led module quit working a couple years ago, not sure why.
I packed it away (along with a few other flashlights) when I moved. I had two flashlights that I used, left the rest packed away. But one of the two also quit working. So I unpacked my other flashlights.
Currently the Little Twisty has a M60F module in it. But it's not very bright with eneloops, so I don't use it.
Truthfully I haven't given too much thought about what to do with it... Though I do have several flashlights that could use a better home (including: Malkoff Valiant Little Twisty 2xAA, Peak Vesuvius Brass, Peak Vesuvius HA, ZebraLight SC53Fc).
