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.
