Great calculator in its category
It has a great build, with a really good display, and is excellent in its price point. The major feature of this calculator that sets it apart from its competitors is its full matrix display, where you can see up to a 3x3 matrix as a whole, which can help you in rectifying erroneous values. It is also non-programmable, which means you can use it in almost all exams that allow a scientific calculator. However, a CW version with a better display and more features is available for just 10 rupees more (as of when I'm writing this review), the reason why I didn't pick it is because it might confuse invigilators if you are taking it to an examination, just because it looks more modern, and much more like an actual phone screen with good icons. However, the CW is still non-programmable and allowed in examinations, but you might have to explain if the invigilator is unfamiliar with the model. It also has a front slide-in protector, which can be slid into the back when using the calculator. The calculator by itself is really thin, and having the protector gives a better feel to your hand (and makes sure you don't miss the protector). I have been using it for more than a year now and it has never died on me, most probably due to the built-in self-charging solar option, which charges the batteries as you use it. In conclusion, I would recommend this product over others in its category any day, but if you are taking an exam in a familiar environment or are ready to chat about the non-programmable character, you are better off with the CW model.

Excellente calculatrice
J’ai acheté cette calculatrice Casio pour mes cours et je suis vraiment satisfaite. Elle est facile à utiliser, les touches sont réactives et l’écran est clair même après plusieurs heures d’utilisation. Elle gère parfaitement les fonctions scientifiques dont j’ai besoin pour les devoirs et les examens, et je trouve qu’elle est bien conçue pour les étudiants. Le manuel est aussi utile pour comprendre certaines fonctions avancées. Le rapport qualité-prix est excellent je la recommande vivement à tous ceux qui ont besoin d’une calculatrice performante et durable.

ممتازه
كتقييم مبدئي: ممتازه واصليه واتاكدت من الاصاله عن طريق Qr code اللي ع العلبه من الخارج ومن ال id تبعها برده ف الداخل عن طريق mode بعدها تضغط zero هيظهر الكود وتقدر تعمل اسكان وطلعت اصليه. بالنسبة لجودتها ممتازه كتصميم واحسن من الموديل الاول القديم الازرار مقعره كدا عشن تبقي مريحه وتصميم واضح ومغلفه كويس من الداخل ببابل عشن الخبطات اللي وصلتني نفس الموديل بالظبط اللي طلبته وكان البائع امازون جبتها ع سعر 945ج ولكن اتخصم حوالي 94ج عشن كان عليها عرض ف عروض رمضان الحاجه الوحيده اللي دايقتني ف التصميم واللي لاحظتها بما اني كنت بستعمل 1nd edition بقالي سنين ومتعود عليه ف لقيت ف الحديثه دي ان الغطاء تبعها لازم الاله تركب من اول الغطاء مش من نصفه زي الموديل القديم هي متعبه شوية خصوصا لو بتشتغل سريع ف الحل وكدا 😂 ولكن كتعود متهيالي عشن جديده فبالنسبالي هتعود ع التصميم الجديد بسرعه كمان من التغييرات الواضحه كمان واللي تفرق الموديل دا عن القديم ان الغطاء بقي تقدر تركبه بالمقلوب والمعدول ع عكس الموديل القديم كان الغطاء مينفعش تبقي كلما CASIO باصه لتحت ولكن ل الجديد دا بقيت متاحه عادي الملمس واللون ودت لحظته روعه واتاكدت من ال ai ان دا مش لون زي ما ال 1nd edition كانت لون ازرق لا دا البلاستيك نفسه اسود للغطاء وللأله نفسها فدا بيدي سحر ف الرؤية والفخامة والجاذبية وكدا زوايا الاله بقيت مربعه برده مش زي ال 1nd edition حاجه كدة شبه سامسونج s24 😁 ودا اللي خلي الغطاء تبعها بيقبل عادي يبقي مقلوب كلمه كاسيو. بالنسبة لنظامها اظن برده انها نفس نظام ال 1nd edition ف المعالجه وكدا وبتاخد مللي ثانية والكلام دا خصوصا لما حساب حاجه كبيره فالحساب هي مش ملحوظه طبعا ولكن اللي اقصد ان المعالج متغيرش هو هو نفس نظام الموديل القديم بس قصاد سعرها طبعا ممتازه لان الانواع التانية ب 2000 وب 5 و 10 فشايف هي معادله مناسبة كسعر وجوده فتستحق باكتساح طبعا بياجي معاها كتالوج ب 3 لغات عادي وحاسس انه وزنها بقي اخف من الموديل القديم هتلاقي فيه فرق كتقييم مبدئي ممتازه والمميزات الجديدة تستحق وسعرها بالمقارنه بباقي الموديلات ممتاز جدا جدا
