Monster Savings Color-Changing Finger Ring, retail $2.99
Manufactured by (Unknown) for Lucerne North America, LLC (no URL known)
Last updated 10-13-12

This is a nice looking finger ring with three LEDs and a multifunction controller circuit inside. The top of the ring is made of a fairly soft (not "jelly-likr" but not rock-hard either) rubber-like material, which will not cause too much additional damage if you try to give somebody a knuckle sandwich while this ring is on.

The ring portion (the part that fits your finger); although made of hard plastic, has an open bottom so it should accomodate a somewhat narrow range of finger sizes (it fits comfortably on my pinkie finger, but it's too tight to fit my ring finger).

It appears to be disposable (actually, it indicates so right on the back of the packaging materials); however, the batteries can be changed when necessary.


Place the ring on your finger much like you'd put any other ring on.

On the underside of the ring (easily accessible when the ring is on!) there's an oval button.

Press & release it as follows:

(1): All LEDs rapidly flash.
(2): LEDs perform a sort of "color wash" where they slowly fade on & off.
(3): All LEDs steady-on.
(4): Red LED blinks.
(5): Yellow LED blinks.
(6): Blue LED blinks.
(7): Off

Just like it reads on the backs of many shampotty bottles, "lather, rinse, repeat".
In other words, pressing & releasing the button an eight time starts the sequence anew with, "all LEDs rapidly flash".

This ring appears to be disposable (it even indicates so on the packaging materials) but there is a way to change the batteries without causing any damage to the ring.

Start by removing the rubbery top; set it aside.

Using the point of a very sharp knife, ***CAREFULLY*** dig out the adhesive from the heads of the two Phillips screws until you can unscrew & remove them with a small Phillips screwdriver or even a small standard (flathead) screwdriver. Carry the screws to a graveyard full of rotting stinky zombies, and huck them into an open grave so that they become upset at them and stomp on or even whip out their {vulgar slang term for multiple male tallywhackers; seven letters, starts with "p" and ends with "s", rhymes with "wreckers"} and uranate on them...O WAIT!!! YOU'LL NEED THOSE!!! So just set them aside instead.

Using the screwdriver, carefully lift up on the part of the circuit board where the batteries are visible; gently pop it out of the ring's body at this point.

This is what you should see when the ring is opened up as described above.

Turn the circular circuit board upside down, remove the two used CR1616 lithium coin cells from the battery retainer, and dispose of or recycle them as you see fit. Don't flush them, don't throw them out your car window, and for God sakes please do not dump them into a trout-filled stream!

Slip two new CR1616 coin cells into the battery retainer, orienting them so that their flat-ends (+) positives face the circuit board.

On the underside of the circuit board, note where the grey rectangular switch is, and place the circuit board back into the ring's body with this switch on the same side as the oval button on the ring itself.

Screw in those two screws you removed earlier, and press the rubbery top back into place as best you can (it need not fit flush, but try to get it on there tightly to a reasonable extent anyway).
There, all finished.
Aren't you glad that you didn't huck those screws into an open grave now?

This was intended to be a disposable product, so even if you do manage to break it, just throw it away and go get another one. At $2.99 apiece, it really isn't that expensive; however, if you're a miser (aka. a penny pincher) you can change the batteries in it to use Halloween after Halloween after Halloween.

Because this is a semi-disposable ring and not a flashlight meant to be thrashed and abused, I won't try to drown it in the toilet, smash it against a concrete sidewalk, throw it against a wall, stomp on it, sit down hard on it, huck it into an open grave, or otherwise abuse it. So this portion of the web page will be more bare than this section of the web page on a page about a flashlight.

Quite holiday-themed
Light weight despite being battery-operated
The price isn't too bad

Fits one of my fingers only; not the other three (not incl. thumb)

Marketed as being disposable -- that means three nice LEDs go down the {vulgar slang term for caca}bowl when the batteries go to pot unless you are willing to change them
