Last updated 03-10-10

This product does not emit light of its own, so the standard review format will not be used and the product will not be assigned a rating. This website is mostly about light-emitting products and test equipment I regularly use, but occasionally, you'll see non-light emitting products on it too if it's something I really like or use frequently.
(This product can indeed be used as a short-range flashlight to illuminate keyholes or to help locate dropped objects within close proximity to {near} you).

This is the Kyocera cellular telephone handset. It is a fairly standard "flip fone", in which a lid over the display & keypad flips open on a hinge to expose the keypad; the video display is on the inner surface of the lid itself.

The unit came with "pay as you go" cellular service from Virgin Mobile.

Use the Marbl like you might use any other cellular telephone: dial the number you want, then press the "talk" key (this key shows a standard telephone handset lifted off the cradle and tilted at an angle -- the telephone handset shown is colored green). When finished with the call, press the "end" key (this key shows a standard telephone handset lying in the cradle; it is not tilted at all -- the telephone handset shown is colored red).

I don't feel like writing a book today, so you'll want to refer to the instructional materials that are furnished with the handset to read about its many other features.

The LCD screen of this telephone in "standby" mode (after you flip it open but before you dial).

Note that the date is indicated as "12/32/09" - it automatically corrected
itself to read "01/01/10" shortly after this photograph was taken.

This is another "standby" screen - the one I currently (as of 03-08-10) use.

Cellular telephone handset was purchased in early-2009 in Federal Way WA. after it was determined that my "California" cellular telephone handset would not function here because there are no cell towers for the MetroPCS service I had been using prior to moving here.

This product was POSSIBLY manufactured in Brazil.
A product's country of origin really does matter to some people, which is why I published it on this web page.
