It gets better: field testing has already been done.

I have been EDC-ing one of these as an everyday "beater" light for over a year. It's always on my belt, in an open sheath, all day, winter and summer, getting bumped around, dropped, and doing the dirty work (unlike my Fenix and 4Sevens 1xAA models which get the white glove treatment).

After a year's beater use, it's still reliable and in good shape, the switch has held up to 20+ cycles a day, the LED has the same output AFAIK, and there are no weird flickers or quirks. Wow.

Ignore the logo, by the way: I now have two, each with a different third-party logo, and they are identical in construction and consistent in build quality. Lots of different sellers slap their logo on these.

The two-hour run-time is pretty much fiction -- you will get the better part of an hour at full power, then a fairly significant ramp-down toward moonglow mode. You can squeeze only so much juice out of an AA. They get along with rechargeable NIMHs just fine, BTW.

The non-metal body (and heavy ribbing) means that they are light and comfortable for holding in your teeth or under your chin for hands-free use. In a cold climate, it won't freeze onto your lips (trust me, not fun).

My only real bug with this light is the relatively short run time. I prefer a light with a secondary low-output, long-run mode for wilderness situations. I also haven't run it for extended periods, where heat could reduce the life of the LED. But it would make a decent, inexpensive backup light to a good headlamp or primary flashlight.

P.S., In Canada, these are available at Canadian Tire (big hardware retail chain). They come on sale once a year for $11-12. The old ones had a Noma label; the new ones have a Garrison label. Identical build/innards, except the new ones have a nicer tint and are available in bright yellow.

EDIT: Need a belt sheath for one of these? Take the $4 nylon belt sheath for the original 2AA MiniMaglite (the sheath with the velcro flap over the lens and the velcro-held belt loop), cut down to size, and fuse the nylon with a Bic. Bingo.
