Bests & Worsts Reviews from Amazon

There are a few cons with this calculator, but due to the price, I will not deduct a star for them. For one, the print on the screen is not as pretty as a Ti and the calculation speed for large calculations may be a tad slower than an 84. It also isnt as easily programmable, but who cares? The functionality of the device is very intuitive and many problems can be done without the aid of the book. The way the menus are designed allows some problems to be done much quicker than on the Ti. For instance, if you are doing probability calculations that involve the combination "C(n,r)" fucntion, that function becomes one of the "function keys". Hence, every time you need to access that function within a problem, it is already there. On the Ti, that function is buried in menus and you have to maneuver through those menus every time you need to access the function, thereby making the problem more laborious. If by chance you ever do need the book, which is inevitable, you will see the biggest area where Casio has a leg up on Ti. The books that come with Ti calculators are notoriously useless and are of little to no help. The Casio documentation, on the other hand, is extremely helpful. Functions are easy to find and understand. The book is well organized with easy to follow examples. Casio could teach Ti a thing or two (or a thousand) about helpful documentation. For [...] bucks, this calculator is amazing! AN UPDATE: I have been using this calculator for quite a while now and there is a point in my review that needs correcting. There are NO functions or calculations that are slower on this calculator than on the Ti-84. This calculator is quite fast and efficient. If I were to lose my Ti-89, my Ti-Inspire, my Ti-84, and this calculator, THIS one would be the first I would replace.
