## i41CX Reviews in Франция

### ***** "Formidable"
Avec la dernière mise à jour 7.6.3, le programme se lance et disparaît immédiatement.
Bug corrigé dans les heures suivantes avec la version 7.6.4.
Excellente application.
-- Ituniax, 2020-10-22

### ****- "I41CX  question"
Comment programmer le point décimal ai lieu de la vigile?
Autrement j'adore cette appli. Je ne sais plus me servir d'une machine conventionnelle.
-- castorsouriant, 2017-07-05

### ***** "Excellent"
Bon retour au rpn et possibilités de cette calculatrice
Excellent forum sur le net également autour dece bijou de techno de l'époque
Reste à trouver la doc originale en français
Encore une fois, excellent travail
Et point important, le support est bien présent
Seul point négatif: il faut acheter la 41+ pour bénéficier de l'import des roms
