A4Tech Optical Mouse, retail $TBA (www.a4tech.com...)
Manufactured by A4Tech (www.a4tech.com)
Last updated 05-25-10

This isn't a laser, flashlight, or other product specifically designed to produce light, but since it uses an LED and that lamp is rather critical to its functionality, I figured "what the H-E-Double-Bendy-Straws" - I'd probably get eternal darnation if I failed to add it to this website because of that LED in it anyway.

This is a three-button computer mouse that uses an optical tracking mechanism rather than a ball. The third (center) button also incorporates a scroll wheel, eliminating the need to mouse over and "click & drag" on the scroll bar at the far right of the document or web page you're on in order to get that page to scroll.

I've had this for a few years now, that's why it does not look brand spanken new in the above photograph!!!

This mouse is actually quite easy to use.

Plug the cord coming from the mouse into any free USB port on your desktop or laptop computer. The computer should almost immediately "sense" its presence and automatically install the correct driver.

At this point, the mouse should now be working.

This mouse is compatible with the following operating systems (according to the web page for this mouse on the A4Tech website as of 05-23-10 {or "23 May 2010" if you prefer}):

Windows 98, Windows ME, Windows 2000, Windows XP, Windows Vista X86 & X64, Mac OS 9.X~10.X.

I've been using it successfully with a KVM switch (a device allows two computers to share one monitor, one keyboard, and one mouse) since at least mid-2006, using a USB-to-PS2 adapter. One of the computers runs Windows XP, and the other runs Windows 98.

This mouse does not use batteries, so I do not have to tell you which part to remove, huck down the basement stairs into the room crawling with thousands of hungry piss ants, and then rather emphatically tell you not to.

Unable to measure current usage due to how the product was constructed.

This Optical Mouse is designed to be a computer peripheral, not a flashlight meant to be carried around, thrashed, and abused; so I won't try to drown it in the toliet tank, bash it against a steel rod or against the concrete floor of a front porch, let my mother's big dog's ghost or my sister's kitty cats spring a leak (uranate) on it, run over it with a 450lb Celebrity motorised wheelchair, stomp on it, use a medium or large ball peen hammer in order to bash it open to check it for candiosity, fire it from the cannoņata, drop it down the top of Mt. Erupto (I guess I've been watching the TV program "Viva Piņata" too much again - candiosity is usually checked with a laser-type device on a platform with a large readout (located at Piņata 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 cannoņata (also located at Piņata Central) is only used to shoot piņatas to piņata parties away from picturesque Piņata Island, and Mt. Erupto is an active volcano on Piņata 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.

In fact, that photograph and spectrographic analysis below may very well be it.

I use this mouse every day, and have used it daily for quite a few years now, and have no problems to report.

This light is not designed to be seen, so this photograph really wasn't absolutely, positively, 100% necessary.

Spectrographic analysis

Product was purchased at a totally unknown time and from an unknown vendor.
I very likely wound up with this mouse sometime in 2006.
