Very good calculator for the average student. It has many functions that TI calculators just don't feature. The overall design is much better than that of any Texas Instrument calculators, and the small details of the calculator are worked out really well. The one thing about this calculator that may be improved is the tightness of the buttons, and the texture. The non- PLUS version of this calculator had beautiful buttons that aren't as loose as these, and allow your fingers to slide between keys much more easily. Overall, this calculator has good design and software, and is a very good buy.
