Calculator works fine but if you are buying it for a level maths just a word of warning, drop it asap or if that isn’t an option then start revision months in advance. ITS SO HARD!!

It's got a good design, good feel and very versatile and functional. It's good quality, and very good to use in school. The display is quite good, only problem is sometimes it could be brighter. The buttons have a good feel.

The calculator's body and buttons are of poor quality, made from cheap plastic. Additionally, no batteries are included, requiring a separate purchase. Weighing around 50 grams or less, it feels very light. The 2-gram plastic sheet for protection makes noise but doesn't easily break.The calculator's body is weak and fragile, necessitating the purchase of a body protector. Valued at less than 15 euros, it's my least satisfying purchase, and I deeply regret it. Delivery took 9 days in Central Europe. Made in Thailand. The calculator's display lacks the necessary quality. I'll thoroughly test its functions and performance and share my findings.

It is a great calculator and it is incredibly easy to use, the only issue I have found is in comparison to the older generations of this product they changed the interface to make it easier to use and with the new interface you just need a bit more time to change settings and formats. Overall great product.

Der Rechner beinhaltet die gleichen Funktionen im gleichen Umfang wie der Casio991de-x.Der wesentliche Unterschied ist, dass noch mehr Funktionen der alten Version 991de-x in verschachtelten Menüs ("Catalog", "Tools", "Funktionsanalyse") verpackt werden, so z. B. sind Tasten für Ableitungen, Integrale, Summen und Produkte schwieriger zu erreichen. Subjektiv ist er etwas umständlicher und unübersichtlicher zu bedienen.Zusätzlich gibt es zwei Zahlenspielereien: Man kann Serien mit 1 bis 3 Würfel oder 1 bis 3 Münzen simulieren und die Würfel jeweils addieren lassen und die Differenz der Würfelergebnisse von 2 Würfeln ausgeben lassen oder die Anzahl der einzelnen Würfelergebnisse oder Münzen anzeigen lassen.Zusätzlich kann man aus einem angegebenen Zahlenintervall einen zahlenstrahl anzeigen lassen oder nach der Angabe einer fiktiven Uhrzeit ein Zifferblatt zeigen lassen und die Winkel zwischen den Zeigern berechnen lassen (Bsp.: 3:00 entspricht 90 Grad).Diese eher sinnfreien Spielereien, die in der Prüfung nicht gebraucht werden, könnten bei einem kleinlichen Prüfern dazu führen, dass der Rechner als grafikfähig und deshalb bei der Anforderung "nicht grafikfähig" als nicht zulassungsfähig eingeordnet werden!
