I bought Casio again because I had it before for over 10 years and I was satisfied. It is quite big as a watch which is positive for me, it is bigger than what I had. However, at night when I press the light, the letters are not readable clearly, as if the screen is too bright and it covers the numbers. This is the most negative thing it has for me.
In terms of quality, the plastic seems cheaper than what I had. The switches to adjust them, at least in mine, are not very accurate, I have to play a little with the switch to get it into the right mode.
The sound is good, as loud as it should be for my ears.
