Impressions:
By far one of the smallest and lightest pocket lights available.
So light it doesn't even seem to exist when placed on a keychain.
They are very bright to start, but with no voltage regulation
circuitry they dim considerably as they get used.
The batteries are replaceable, but the screws are so tiny
- size 0 Phillips - it can be a real chore. The batteries
are a readily available coin type. The white light runs on
2 x 2016 batteries for about 12 hours, growing dim throughout
the batteries' serviceable life.
The light is not even water resistant. Water will simply
pour in the light around the slider switch on the top. If
it gets wet you can "spin dry" the light by hooking
the keychain on a long lanyard and spinning it above your
head. Even better would be to open the light and coat all
the internal parts with a thin coat of dielectric grease to
give it some degree of water repellence.
The slider switch is tiny and you need to use a fingernail
to turn it on and off. This may not work too well for some
people. The switch can get "loose", requiring the
user to open the case and bend the contacts.
Comes in a wide variety of colors but only white allows full
spectrum vision (best for distinguishing colors).
The LED is exposed and may be subject to damage if dropped.
It can be protected using a short length of 5mm clear aquarium
tubing cut slightly longer than the LED and slid over the
top of the LED.
Update: I'm bumping this up to 3 Stars (from an original
2 Stars) just because it's so darn handy.
+ + + Pluses: Very tough, Good light up close, Lightweight
- - - Minuses: Not water resistant, Tiny constant
on switch, Requires tools to change batteries, battery change
difficult in general
