Fine, powerful, easy to use, beautiful (a little messy on the screen, a trace is seen)! But the battery discharges too quickly, and I think that this calculator is not supplied with an AC charger (USB only) is somewhat restrictive, especially given the price of the calculator. It would also have been delivered with a full printed manual, the simple pamphlet "Start Guide" is a little light compared to the performance of the calculator.
Overall, the calculator is fine, but the accessories with which it is shipped (ie a USB cable, a cable for connecting with another calculator, and a leaflet as a guide) are a bit light. This does not prevent, I do not regret my purchase!
