The Osram 445nm Blue Kaleidoscopic Portable Laser (hereinafter, probably just called a "blue portable laser" or even just a "blue laser") is a royal blue-emitting, directly-injected diode laser. That is, it produces deep blue laser radiation directly, without the need for messy, fragile nonlinear crystals like those green laser pointers and the amberish-yellow and slightly greenish-blue ones as well. It uses a pair of AAA cells to feed its laser diode with.
It also features a removeable "starfield" projector head that projects hundreds of 'stars' in hundreds of different patterns that you can select by rotating the head.
This laser has a measured power output of 171mW at 448nm in the blue part of the spectrum.
This is the reason I call it a "portable laser" on this website instead of a "pointer". Lasers designated as "pointers" must -- by US law anyway -- have a power output that does not exceed 5mW.
It comes in a handsome aluminum body with a black matte finish and brushed chrome-colored accents.
SIZE
To get the laser to turn on, first load it with two AAA cells (see directly below), and THEN you can go set fire to the dead wingless legless fly you found in your box of raisins*...er...uh...go do some "scientifical" experiment or project some stars.
Aim the laser well-away from your face first. Press & hold the chrome-colored button on the barrel to turn the death ray...er...uh...LASER on; release the button to neutralise it (deactivate it).
To project a starfield, first be certain that the starfield projection head is screwed onto the laser's "business end". Activate and deactivate the laser as described directly above.
To change the displayed stars, simply use your hand to rotate the star projection head clockwise (as though tightening it); the projection that you last used will remain even when you put the laser away and then go to use it again thanks to its fairly stiff action.
*This is Worm Quartet...one guy (Reverend Shoebox) and three worms.
The song "Find The Dead Wingless Legless Fly In Your Box Of Raisins" is from the album "Faster than a Speeding Mullet".
To change the batteries in your blue laser, unscrew the laser at the halfway point, throw the front portion in the {vulgar term for feces}bowl, yank that silver handle on the front of the cistern down, and flush it away...O WAIT!!! THAT'S THE GOOD PART!!! So just set it aside instead.
Tip the used AAA cells out of the barrel and into your hand, and dispose of or recycle them as you see fit.
Insert a pair of new AAA cells into the lower half of the barrel, nipple-end (+) positive first. This is the opposite of how batteries are installed in most flashlights, so please pay attention to polarity here.
Screw the two halves back together, and be done with it.
Aren't you glad you didn't flush away that front half now?
Unable to measure current (amperage) due to the way this laser was constructed.
This is a self-contained laser , and not a flashlight meant to be carried around, thrashed, trashed, and abused - so I won't try to drown it in the toliet tank, bash it against a steel rod or against a concrete porch, let my mother's big dog's ghost, my kitty cat, or or my sister's kitty cats piddle (uranate) on it, run over it with a 450lb Quickie Pulse 6 motorised wheelchair, stomp on it, use a small or medium ball peen hammer in order to bash it open to check it for candiosity, fire it from the cannoñata, drop it down the top of Mt. Erupto (I guess I've been watching the TV program "Viva Piñata" too much again - candiosity is usually checked with a laser-type device on a platform with a large readout (located at Piñata Central {aka. "Party Central"}), with a handheld wand that Langston Lickatoad uses, or with a pack-of-cards-sized device that Fergy Fudgehog uses; the cannoñata (also located at Piñata Central) is only used to shoot piñatas to piñata parties away from picturesque Piñata Island, and Mt. Erupto is an active volcano on Piñata Island), send it to the Daystrom Institute for additional analysis, or perform other indecencies on it that a flashlight might have to have performed on it. So this section of the web page will be ***SIGNIFICANTLY*** more bare than this section of the web page on a page about a flashlight.
This is a directly-injected laser though (which by their very nature are more rugged than DPSS lasers!), who's active components are the inverter circuit, the laser diode, and the collimating lens. So it should withstand accidents better than a DPSS (diode pumped solid state) laser - the type of laser assembly found in deep red (671nm), yellow (593.5nm), green (532nm), and light blue (473nm) laser pointers. These lasers have several additional components (crystals, filters, etc.) in the optical train, and you can knock them out of alignment by doing little more than looking at them the wrong way. And if any of these components are knocked out of whack, you'll no longer get your deep red, yellow, green, or blue laser beam.
Though you still do not want to intentionally drop your blue-emitting portable laser because it's a precision optical instrument.
The biggest downside to this laser is the fact that while this is clearly a CDRH Class IIIb laser (making it somewhat dangerous!!!), there are no safety features at all that are normally required in Class IIIb lasers; e.g., there is no "emissions" indicator, no startup delay, no interlock of ANY type, and no mechanical beam shutter. This laser behaves like a Class IIIa laser pointer in this regard, which I believe is a rather severe no-no!!!
Beam terminus photograph of this unique (well, "not-so-unique" now) laser on the target at 12".
Beam image bloomed a bit even though it was daylight and photoflash was used when the photograph was taken. Those white and purple colors doe not actually exist.
"Not no way, not no how" as they say.
Beam terminus photograph on a wall at ~10'.
Again, that white color does not really exist, and beam image bloomed somewhat despite photoflash having been used.
Beam terminus photograph of the laser at ~20" when the kaleidoscopic head was put on.
Yet again, those purple & white colors do not really exist.
Attempted barbecue...er...uh...ATTEMPTED PHOTOGRAPH of the unit's beams as might be viewed a bit downrange.
Vapours from the iSMØK Electronic Cigarrette were used to make the beams visible.

*"Uranated" - infused with an oxide anion of uranium, *NOT* piddled (peed) on.
Commonly referred to as "Vaseline glass" because it has
a distinct pale yellow-green color when not being irradiated.
Note spelling: "urAnated", not "urEnated","urInated",
"urOnated", "urUnated", or sometimes "urYnated".

UPDATE: 00-00-00
PROS:
Color is very radiant & unusual for a pen-style handheld laser
The price is right!
Has kaleidoscopic starfield projector
Uses batteries that are common and relatively inexpen$ive
Color is very radiant an unu...o wait, I said that already!!!
CONS:
No laser warning labelling of any type -- that's what nocked ½ star off its rating
No safety features required of a CDRH Class IIIb laser -- this is what lopped another ½ star off
