Casio FX991ES Plus Dual Powered Scientific Calculator. 5 5 5 6
Very helpful! Should have bought one before! I recently sat my GCSE maths exam, and I used another scientific calculator. I subsequently bought the Casio FX991ES and I should have bought one earlier. It is user friendly, fun to use and helps you understand calculations. This calculator is not necessarily an easy option for answering maths questions. The calculator helps you to apply what you know. Excellent for calculating fractions, and gives you the option of an answer in fraction or decimal form. Very useful indeed. 08 July 2014
Calculator for A levels Comes with an operating book which is written in very tiny fairy writing. If I were designing a calculator with multiple operations I would make the print much larger on the actual calculator. To use at a desk where you are going to relax to use it. If you are doing everyday basic sums, on the move then yes tiny is useful to slip in your pockets. I am doing a self study as a mature student out of curiosity. 15 April 2014
Complex Function Features are Great Excellent calculator with easy to use functions and excellent screen. 30 March 2014
calculator very happy with this prduct very tactile and good quality at a good price 22 February 2014
All you will ever need - and more! You only need the extra features of this calculator if you're going to do really advanced stuff - A level and beyond. For most students one costing half as much will do all that is needed. A little more positive key press would have been nice. I've always though Casio was the best to use. 20 February 2014

Since you have confirmed that this calculator cannot do recurring decimals, why are you continuing to advertise this calculator as being able to do "recurring decimals, Prime Factorisation and Verify"

For this calculator to have these abilities, it would have to be the "FX991ES Plus C" not "FX991ES Plus. If it does have these abilities, then you are displaying the wrong image for this calculator because :- the "VERIFY" function should be above digit "6" : - the "recurring digits" function should be in red above the square root key : - and prime factorisation key "FACT" should be written above the "degrees minutes seconds "key.
