Manufacturer: Logitech. A full size, durable keyboard and high definition optical mouse that put the things you do most just one touch away with instant access to play & pause, volume, internet, email and more! The keyboards bold, bright white characters make the keys easier to read which is perfect for those with less than perfect vision. They’re less likely to wear off, too! You’ll also enjoy a comfortable and quiet typing experience thanks to the low profile keys that barely make a sound and the standard layout with number pad means you won't need to retrain yourself to use it. There is no need to touch a mouse to launch your email or calculator, or put your computer to sleep as you’ve got instant access right from your keyboard. As a further bonus, liquid drains out of the keyboard, so you don’t have to worry about ruining your investment with accidental spills. The keys also last up to up to 5 million keystrokes so you can keep typing long after many keyboards have called it quits. The MK200s included high quality mouse ensures an enjoyable user experience with a smooth and responsive cursor control with its high definition optical tracking at 1000 dpi. The sculpted, ambidextrous shape feels good in either hand, so this combo is perfect for both left and right handers. Requires two free USB ports and is compatible with all Microsoft operating systems from WindowsXP onwards and Linux kernel 2.6 or later.
