Customer Review

This calculator can until now everything I need in the study (mechatronics). Since I have worked previously with a Casio calculator at school, most of the features were easy to find, the rest is fairly self-explanatory.

The only complaint is that the keys have something much play in the slot in the chassis. But this is really just an optical problem, it does not limit the operation.
