Very Good , Colour is perfect and unique

The calculator is pretty nice the brightness is slightly low but the design is nice and good for icse a blue case is provided with it

Excellent calculator even good at looks and latest version to use in engineering

Very Good Product. Works perfectly

Quality was really great and colour is also fresh. Must buy product

good

Very good if you specifically want this version of product. Been using it since 4 years. Every calculation for BCA course (and most probably BTech, MTech, MCA or any technical course like this) can be performed with great feature of backspacing just like windows notepad. Its straight like windows notepad tho the font might not be the best updated one that other versions may have. The display quality is very nice tho, but it may get technical at times for complex calculations. For speed i say its moderate, not blazing fast calculation and it could've been better.. tho it is perfectly fine unless you're not a nerdy looking for the as seamless flagship experience possible. Battery is like - ive not replaced the battery since ive bought it (~4 years from now). For durability

It was real one but casio made the calcualtor quality low,that's it.

الالة جدا ممتازه وماركة كاسيو مضمونه وتقدر تتاكد من الكود الي بالكرتون من جودة المنتج ورقم التسلسل والمواصفات. اصلية

Ja, ich bin Zufrieden

Une super calculatrice avec beaucoup de fonctions dont les approximations des intégrales et des dérivées qui sont assez rares sur des calculatrices non graphiques ainsi que toutes les fonctions usuelles. Je préfère certaines autres casio pour la répartition des touches, mais il suffit de beaucoup l'utiliser, rien d'impossible. Autre bon point : elle fonctionne au solaire et aux piles, donc beaucoup moins de risques de se trouver sans calculatrice à un moment important. La capot est parfait, la couleur change du sempiternel vert de casio. Pour les physiciens/chimistes il y a même les constantes physiques généralement utilisées, donc au lieu de devoir sortir son téléphone en cas d'oubli, elles sont à portée de main. En somme une calculatrice géniale, un peu dure à prendre en main suivant la calculatrice que vous avez eu avant, mais rien d'insurmontable, et une calculatrice super pour tous les âges.
