I bought this calculator to cover the electronic mathematical needs of a private student studying for an A-level in mathematics. I find it aesthetically pleasing and I much prefer the keyboard with light silvered background. the display is clear and the digit size is nearly double the size of the -ex classwiz! I use it regularly and every day. There are a couple, probably literally two, drawbacks with this calculator. The first is that it doesn't display a cumulative binomial distribution table. the second, which probably applies to most advanced scientific calculators today, is that its not possible to change the exponential coefficient to a negative value after it is entered. Admittedly this is not a major problem and a process that's fairly easy to remember.

Does a lot of really usefull functions but sometimes takes a bit of time calculating some bigger integrals. That being said it can solve definite integrals that online calculators can't. Also the buttons arent as fast to press as the pure mechanical buttons found on other calculators. I still give it 5 stars because the features to price ratio is excellent.
