For its capabilities, it's worth every cent. Just be aware that this particular computer cannot be used for integral/differential calculus (not a negative, but important to know before purchasing). It has been a lifesaver for me in the past two years for simple calculations as a scientific calculator. The only potential issue might be the screen resolution as the shift and alpha locks are not easily distinguishable. 4/5 due to resolution, I've had it since high school and now I'm in university.
