This is a very diverse scientific calculator with a wide range of functions. It is quick and effective for your calculating needs. The one downside is that the buttons are not very sensitive. In this aspect, while entering a large number of digits, the calculator will often misread or even miss the digit all together leading to a huge error in your final result. This can be alleviated by slowing down, however, for most purposes, the calculator will be used very quickly. This can cause delays as calculations must be redone to find the initial source off the error. The wide variety of functions also causes some confusion if you have not been exposed to Texas Instruments before hand. Casio users will have the most difficulty in the transition.
