Perfect! But pricey 2

For installation is simple: you plug the USB dongle and you turn the keyboard and as a bonus you can download the set point for more options.

As for the keys: pleasant comfort and silent keys, and no bugs, very responsive.

The presence of light is perfect, the lights is really what made me want to buy it and it is perfect too.

As for the battery, I still can not comment because I received there a little less than a week.

To conclude: A perfect wireless keyboard that lights up, but it will take or put a price to acquire it.
