Casio FX-991ES Scientific Calculator

Does exactly what it says on the tin, but:

The basic functions to store and recall a memory value are quite awkward.

Also, boolean operators (OR,AND,XOR, etc) are not called via direct buttons which can be annoying for the few times that i need them.

The large screen is good and the history replay feature can be useful.

This is a wonderful Scintific calculator. I brought it for my daughter. The main atraction is the display and solar panel. Plenty of functions and options, cheapest price I have seen in the net. Send it to Australia, still the cheapest.

The calculator is excellent, and I got it for only £8.51. I find it easy to use and it handles everything I can throw at it. It is also good for the environment - an important feature to consider when purchasing anything, as it has solar panels.
