Great CAS... slightly overcomplicated interface... great school calc.

Summary: Even ebay, doesn't know which one is which calculator, as I see the picture of non-CAS calculator associated with this item. CAS vs non-CAS... FUNDAMENTAL DIFFERENCE. CAS calculator can do a lot of math symbolically. What that means is that it can solve equations with variables in them, it can do all the algebra for you. It's truly something else.
Summary: I'm using this for my AP physics class and it is absolutely perfect! Its even perfect for my PreCalc class, and I really wish I had been using it before my senior year. I bought the calculator refurbished, but it may as well have been brand new!
Summary: I needed this calculator for college. It works great! I got it at less than half the price than I would of from a local chain store. It is a little picky because each command has to be put in just right but all the added buttons make it easier. Also it has really good graphing features and can be plugged into a computer.
Summary: Love it will love it even more when I learn how to use it. An instruction manual would have been helpful and I would have appreciated the real version of the software so I could register my calculator. But no they show a copy of the real version and send you a copy. "FALSE ADVERTISING.
Summary: This product was exactly what I wanted: a graphing calculator. This particular one required a software update before it could graph 3D equations and planes and the like. Overall this calculator is very useful for multivariable calculus and calculus in general. Highly recommended.
