One of the keys on my trusty old fx-260 had become erratic (it's over 20 years old, so I can't complain) and I decided to upgrade to the state-of-the-art fx-991ex. Unfortunately, I don't like it. First, my minor gripes: (1) It's too big; I love the pocketable size of the fx-260; (2) the keys feel like chiclets and make a rattling sound when pressed; (3) the mottled surface texture makes the alternate key labels hard to read, especially the blue ones - practically impossible except in very bright light - what were they thinking? (4) The slide-on cover is too loose-fitting, slips off by itself. But more importantly, (5) I find that I don't like its main attraction, the V.P.A.M. entry method. The display is pretty and I like how the entered formula remains on display together with the answer - but it's cumbersome: expressions used in everyday math and science require more clicks than with the "immediate entry" method. And the whole menu system - who uses a calculator for spreadsheets or matrix calculations? Come on. -- The fx-991ex is a very cool calculator and I'm keeping it to show off to family and friends, but I got myself a replacement fx-260 for everyday use. (Secretely, I want a SwissMicro dm42, but they're just too expensive.)Read full review

Tweaked version of its predecessor, the fx-991ES Plus, and worth it just on looks alone! Appearance is almost a work of art and with its attractive, main menu icons, looks stunning. It is, however, highly functional as well and possesses amazing features for the money, including two unique ones: a polynomial inequality solver and a ratio solver. Don't get too carried away though! This is not a true graphical calculator, it isn't programmable, can't be connected to a computer, and, unlike the fx-9860GII, you can't add a range of apps. Also, they've improved the statistical functions but these are no match for what the fx-9750GII or fx-9860GII offer. Also, don't expect the same build quality, either! A great little calculator though and well worth the low price on eBay.

I bought this calculator because it has variable memories, which means you can save values for letters A, B, C, D, E, and F into the calculator to use later on. I was having trouble memorizing a certain constant, so I saved it in my calculator. It also comes with lots of constants pre-programmed. I also love that i can go back and edit formulas after i get an answer. Also, the QR code generator is fun!

It is very easy to use, so many useful functions that make calculations easier than ever. I am glad I opted for this upgrade.
