Zoink! "Laser Fun 'N Run" Pet Toy, retail $4.59 (www.sergeants.com...)
Manufactured by: (Unknown) for Sergeants (www.sergeants.com)
Last updated 03-28-14

The Zoink! "Laser Fun 'N Run is a small laser that is designed to be used as a cat or dog toy -- that is, you're supposed to direct the laser dot at the ground and allow your pet to "chase" it.

It uses three LR44 button cells; "the laser pointer battery" -- the same power source used in most other "keychain-style" laser pointers and portable lasers.

It comes in a handsome greenish-yellow body with an animal's paw protruding from the tailcap to remind you that it was designed as a cat or dog toy.


To get the laser to turn on, first be certain that there are a trio of LR44 button cells installed -- it does come with them installed but you need to dump the batteries and remove that white insulater between two of the cells first; this insulater helps ensure that the batteries don't become dead during transport, storage, or display (where customers may attempt to activate it (possibly for long periods of time at that).

Press & hold down the button on the barrel and direct the laser spot on the floor or low on the walls so that Muffin or Fido chases it. Continue to have fun with your pet for as long as you wish. Do allow them to "catch" the spot with their paw from time to time so that the pet does not become discouraged and subsequently become disinterested in the toy.

Release pressure on the button to turn the laser back off.

To change the batteries in this pet toy, unscrew the tailcap of the laser, throw it into plastic cat toliet (litterbox) so that the cat comes in, sniffs at it, and then proceeds to squat over & uranate on it (or throw it next to the mailbox so that the family dog finds it, sniffs & snuffles at the damn thing for a moment and then lifts his leg on it) ...O WAIT!!! YOU'LL NEED THAT!!! So just set it aside instead.

Tip the three used LR44 button cells out of the barrel and into your hand, and dispose of, recycle, or recharge them as you see fit.

Insert three new LR44 button cells into the barrel, orienting them so that their slightly raised sides (-) negatives go in first.

Screw the tailcap back on, and be done with it.
Aren't you glad that you didn't huck that tailcap into the cat box with the fudge bunny on the surface of the litter now?

Current usage measures 20.41mA on my DMM's 40mA scale.

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, her kitty cats, my kitty cat, or my sister's kitty cats piddle (uranate) on it, run over it with a 450lb Quickie Pule 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, who's active components are 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 yellow (593.5nm), green (532nm) and 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 nocked out of whack, you'll no longer get your yellow, green, or blue laser beam.
Though you still do not want to intentionally drop your red-emitting laser because it's a precision optical instrument.

I did however, perform "The Knife Test" on it. When I slid the blade of a large folding knife transversely across the barrel near the tailpiece, (with rather surprising difficulty) I exposed the bare Metalimpmon...um...the bare Metalgallantmon -- er -- the bare Metalsakuyamon -- um that's not it either...the bare Metalmegagargomon ("Moumantai!")...er...uh...wait a sec here...THE BARE METAL (guess I've been watching too much Digimon again! Now I'm just making {vulgar slang term for caca} up!!! ) where I had PRESSED IN whilst simultaneously dragging the knife blade.

Power output measurement
Power output: Peaks at 6mW briefly, then stabilises at 5mW.

Power output measurement
Power output after a short time of battery discharge: Appears to be fairly stable at 4mW.

These measurements plus the short-term stability analysis below were performed on a LaserBee 2.5W USB Laser Power Meter w/Thermopile.

Power output measurement
Short-term (~740 seconds) stability analysis.
Considering the small size of its batteries, the decrease to less than 1mW was fully expected; the unit was still lasing strongly when the test was complete.

Spectrographic analysis
Spectrographic analysis of the laser diode in this product.
Wavelength appears to be ~655nm, which is within specification for the type of laser diode used in this laser.

Spectrographic analysis
Same as above; but spectrometer's response narrowed to a band between 654nm and 667nm to pinpoint wavelength, which is 655.730nm.

Test unit was purchased at a nearby Safeway in Federal Way WA. on 07-02-12 (or "02 Jul 2012" or even "Jul 02, Twenty Stick-Very-Twirly-Stick" if you prefer).

UPDATE: 03-25-14
My aunt has become worm food and my brother's girlfriend has adopted her cat, so I once again have this product at my disposal.

Uses inexpensive and readily available batteries
With only brief use, low power output makes this laser kosher to use as a cat toy (that's what it was made for, you silly goose!!!)

Power output starts out a bit high on new batteries (that's what nocked that last star off), but quickly sags to "pet-eye safe" levels (see directly above)
