The Logitech K400r is a comfortable and convenient, durable Windows wireless keyboard with nice feel and a built in multi-touch touchpad. The keyboard is compact and perfect as a replacement keyboard or to get the cables out of your life. They're also a great size to fit in your laptop bag and give you a remote keyboard for presentations.Just insert the Logitech Unifying USB receiver into your computer and you're off and running, turn on the keyboard, and you're off and running.This is a Logitech mainstay and sells today on Amazon for $64.99 from the Logitech Store. The item ships with the keyboard and Unifying Receiver (small USB dongle). Batteries not included.I am also selling new, open box models of this keyboard at a slightly higher price if you'd rather have an unused item.(Note: The USB extension that originally shipped with these keyboards is not included. It is unnecessary and was intended to make it physically easier to reach inaccessible USB ports on older computers. We found it annoying because it sticks out too far from the computer.)
