For one thing, the Powerful Red Laser Pointer 5mW isn't "5 milliwatts" at all -- not even close!!!
Go on, take a guess at its power output.
NO WAY HOZAY! TRY 98mW!!!
If it were labelled properly, I'd consider this laser being this much overspec to be a good thing.
Now, back to our regulary scheduled programming, already in progress.
The Powerful Red Laser Pointer 5mW is a pen-style portable laser. It has a directly-injected red diode laser and a collimating lens, and feeds that diode with a pair of AAA cells that you supply yourself.
It comes in a handsome aluminum body with a pocket clip.
Because this is a laser, you should not shine it into your eyes, other people's eyes, pet's eyes, etc. Just use a little common sense here, ok?
* It is ***NOT*** 5mW -- it's almost 100mW!!!
To use your new portable laser, feed it first (see below), and then you'll be ready to burn holes in a black plastic garbage bag or something (never, ever EVER use this particular laser as a pet toy!!!)
Press the button on the barrel and hold it down for as long as you want or need the laser beam, and release it to neutralise it (shut the unit back off).
Don't aim the laser at your face when you push the button, otherwise you might hit yourself in the eyes with the laser beam, and that
wouldn't be very good at all.
This portable laser requires two AAA cells, which are not included.
To change them when necessary, unscrew the laser at the halfway point, throw the front half in the cat's litterbox, and use the "pooper scooper" to bury it...O WAIT!!! THAT'S THE GOOD PART!!! So just set it aside instead.
Tip the open end of the lower half of the barrel into your hand, and dispose of or recycle the two AAA cells that come out as you see fit.
Place two new AAA cells into the lower part of the barrel, orienting them so that their nipple-ends (+) positives go in first (this is the opposite polarity of how the batteries are installed in most flashlights, so please pay attention to polarity here) and screw the front half back on.
Aren't you glad you didn't huck that front piece into the plastic cat toliet now?
Unable to measure current usage due to how the laser was constructed.
The Powerful Red Laser Pointer 5mW is not water-resistant or submersible, and probably would not withstand being stomped on or run over either. But it should not break just through normal use and very minor accidents.
Since portable lasers like this are not meant to be stomped on, run over, drowned in the commode, or otherwise abused, I will not inflict those sorts of punishments upon this one. So this section of the web page will be a bit on the bare side. :-/
The portable laser emits a red beam measured at 662.950nm in wavelength, and has a measured output power of 98mW -- so it's definitely ***NOT*** "cat eye safe"!!!
Measures 98mW on a LaserBee 2.5W USB Laser Power Meter w/Thermopile.

Spectrographic analysis of this laser.
Spectrographic analysis of this laser; spectrometer's response narrowed to a range between 660nm and 670nm to pinpoint wavelength, which is 662.950nm.

A beam cross-sectional analysis would normally appear here, but the computer that hosted the ProMetric 8 Beam Cross-Sectional Analyser was destroyed by a lightning strike in July 2013 (the monitor had this big-ass hole blown right through its viewscreen); although a replacement computer is already en route (it just came several days ago actually), there's a fairly significant chance that the beam cross-sectional analyser itself was also wiped out because both the computer & test instrument shared the AC power at the same outlet on the same power strip.
Test unit was purchased on Ebay on 11-13-13, and was received on 11-16-13.
Nice looking case
Beam is clean with no unwanted artifacts or speckling in it
