Tadellos.
Er funktioniert einwandfrei, und wenn jemand das zweizeilige Display im klassischen Stil schätzt ist dieser Rechner eine gute Wahl. Man merkt aber schon anhand des Funktionsumfangs dass er schon in die Jahre gekommen ist und definitiv ein Design der 90er ist. Da ich aber Rechner sammle bin ich froh einen neuen abgestaubt zu haben.

Calculator GOAT
Been using it for almost 3 years, still as good as new. Provides almost all features required for any engineering exam. It has no such programming or very good memory features, so it is allowed for all engineering semester exams. Great product overall.

Solid calculator for students
Solid calculator for students — does the job without drama As an engineering student, the Casio fx-991MS has been a lifesaver for me. It covers all the essential functions — complex numbers, matrices, integration, stats, etc. — without going overboard. The button feedback is decent, the display is clear (dual-line is a plus), and it runs on both solar + battery, so you never get stuck during an exam. It's not flashy like the fx-991EX, but it’s reliable and familiar. And honestly, sometimes that’s all you need. It’s accepted in most Indian exams (JEE, GATE, etc.), which is a big win. Only downside? No high-resolution display and feels a bit "2000s retro" — but that’s part of the charm. TL;DR: Great value, trusted brand, exam-ready — go for it if you don’t need the fancy features of the newer models.
