Reliability backlight keys ...

Beau keyboard battery that holds well the silent burden without being exceptional but disappointed with backlit keys that works randomly and do séclairent more after only 4 months "at 2 hours of use per day on average," the fault of no luck may be but it's been almost 90 bitching, lighting of the keys was a major reason for this purchase now I have more than to hope not to be disappointed with the service of Logitech, stay tuned ....
