ChristianI received a letter from Canada today with a light spreader for my F-91W and installed it straight away. π

Velocipede RiderOk, I did the light spreader mod on the #CasioA158W that @ahojo gave me today.

It's better, right? π
P.S. If you have a Casio with a 593 module (e.g. F-91W, F-84W or A158W) and want to do this yourself: https://www.etsy.com/listing/1448973768/back-light-spreader-for-casio-f-91w-a
A question for owners of Casio A158W, F-91W and F-84W watches.
Aesthetics aside, is the basic LED lighting on the module 593 actually usable for how you use your watch?
Yes
No
Sometimes

So Casio fans, there is often talk about how module 593's major failing is its backlight. And yes, it is pretty weak and uneven. I too have thrown shade at it and yet, if I am totally honest I don't recall ever having struggled to read it in real life.
While in photos it often comes out looking totally unreadable, I find that with the naked eye (in the dark at night), I have always read the entire display just fine.
Is this just me?
