I always like Casio watches since I was a kid I already wore casio watch
that time no much graphics just the time and a little light bulb, purchased
this as a gift I don't expect much with this watch, for the price don't expect
its G-Shock at least long life battery will be good.

whats good?
-Price, durable for normal use
-Tells time :) stop watch, alarm
-Led light
-50m water resistant but this is not water proof
 (Means safe on rain,sweat,shower, accidental fall in the swimming pool :)
-10 year battery life means normal use, keep using the light will decrease life

Other info.
This is small watch-photo appears bigger, screen size is between 1x1inch,
ILLUMINATOR was engraved in the watch, when carefully checking it
I noticed this is not illuminator technology this is just a simple LED light
(I know what is an Illuminator the whole screen backlite will glow)

Some minor issues:
-not Illuminator light technology
-This is common to watches with resin bands, they don't last long
-some flaws with the design specially in the area where the resin band
 attached and spring is connected they easily broke.

If you want a more durable watch go with the casio G-shock,
well you will get what you paid for.

I recommend this watch if you want to spend less than 15$
