    After my husband accidentally bought the German version, I bought this one for my son making sure that it was definitely the U.K. version.
    My son says it’s good.
    I will take his word because he knows what he is talking about when it comes to gadgets and maths.

    The previous one which you can still get had a better ascetic look and feel. This one uses a menu system especially for formatting and there are enough changes to warrant a look at the manual. In some cases I felt that using the menu system was sometimes unproductive.

    Once I’m used to the new format (which is now the standard for Casio apparently) I think this will be a more logical calculator than previous versions. Very powerful. (Worth looking at Youtube Videos before you buy if you’re not sure…

    I had to buy this calculator for my son, it is useful for A LEVEL Maths student as recommended by their teachers. I compared the price elsewhere and it was priced reasonably.

    When it arrived I was a bit confused as it looked far too new to be used. It came in perfect condition with only the on button pushed in a bit, but that was expected as it’s used. Overall I would recommend.

    5.0 out of 5 stars Perfect conditio

    Purchased this for my daughter who is in the middle of her A Levels. This is the latest version and replaces FX-991EX. Daughter has said it very easy to use, the screen is very clear and is does everything she needs.
    She has no complaints at all!

    Golden Review Award: 25 From Our UsersOutside of a graphing calculator, which is a much more expensive and complex proposition, this has to be the best you can get. Casio has spent years refining the way these things work, and it shows. The keyboard, for instance, is faultless. The display, considering it’s not backlit, is very clear, and higher resolution than in previous models so you can have more rows in a table or spreadsheet. It’s a very fast calculator too, with most operations happening instantly. Mostly it works on solar power, and there’s a little ‘sun’ icon to tell you this is happening. If the light’s too dim, the LR44 backup battery will take over, and since this is just about the most widely available button cell battery, you should be able to replace it easily and for peanuts.

    The range of functions on offer is amazing — almost too much until you get your head around them. Might be worth watching some YouTube videos for this. There are quite a few on this calculator and others that work like it does. One cool feature is the ‘QR code’ creator that puts a QR code on the screen you can scan with your phone to get graphical representations of functions through the Casio app that you would be able to put into projects. Nice.

    If you’re tempted to get a cheaper brand to save a couple of quid, don’t bother. This is such a low price you may as well have the best. You won’t get the great keyboard with a cheaper brand, or the speed, or the cool carbon-fibre effect body. Casios are always well built and last forever. This one weighs nothing but feels good and well built although the hard case it fits into is a little bit rattly and being white will show dirt.

    My only other criticisms are that some of the text on the keyboard is a bit too small to read comfortably, especially on the textured surface, and the same thing applies to some of the text on the screen too, like the list of scientific constants. And this comes in a blister pack that you have to destroy to open instead of a simple box you can keep. Small beer.

    Really, this is about as good as it gets. It’s outstanding. Just get one.
