I am very pleased with this keyboard, the affected key is very nice with French touches. The sensor turns the keyboard works very bien.Si the keyboard battery is worn out simply plug the USB cable provided and continue to work time to load. There is also an on / off button which mutes if one uses it more, too bad there is no light that indicates that one is always known ON. J "often forgets to turn it off, despite that it's been over 2 weeks that I served and battery lights are still up. The only problem I noticed is on the numeric keypad. Often when I hit a figure nothing written as it is not active at the start of the keyboard and no LEDs indicates, damage. That's why I took off a star. Despite this detail I recommend it everyone.
