Very good calculator. Canon comes with a suede cover. Contrary to the description, the calculator does not use AAA battery but a button battery, it's not really a problem. Very good quality, aluminum rear, and white button that stand slightly, it is really beautiful (much more than my previous IT and Casio, and the HP 300s +, though it was beautiful lacquered black but which "aspired" fingerprints).
The buttons are very soft, and they remind me of Pad Cube's remote Canal +, which were not apparent, but was really good to handle.
The calculator contains a remote converter, with a graphic menu or the measurement type is selected (kilometers, miles, feet, etc ...). The "Apps" menu is practical.
That's all, do not hesitate to ask for more in the comments of this commenting ;-)
