This Labtec wireless keyboard and mouse functions very well for the time I have used it and has proven to be a very good purchase. It is a robust set with good design and decent ergonomic consideration for its price range. The keyboard has strong build and key operation is satisfactory remaining consistent in key response over time. Extra keys are provided for media playing, application launching and internet shortcuts. The mouse is of a good weight and feels sturdy in construction with a lighting scroll wheel when operated. Set up was easy and I recommend using rechargeable batteries in both the keyboard and mouse even though neither are power hungry. The signal to the USB dongle provided is quite strong and can travel several feet. The Labtec wireless keyboard and mouse operates under Linux as well as Windows operating systems. I recommend this keyboard and mouse set for its durability also.
