I am using it for my engineering studies and it offers all the functions I need. Buttons are of good quality except I think the on button which is small but overall have a good button quality. It has solar charging too and you won't need to change the battery often. You can carry it in your pocket. You can also change the contrast of the screen for better viewing at different lighting. Casio has made a truly wonderful product.
