Customize your computer with this Logitech wireless keyboard. Laser-etched backlit keys let you work in virtually any lighting conditions, while the proximity sensors detect your hands to power on the backlights. The PerfectStroke system allows for whisper-quiet, responsive typing. Featuring a unifying receiver, this Logitech wireless keyboard lets you connect one or many mice with just one USB port.
Overall, this is a great keyboard. I'm a heavy user and the rechargeable batteries did not require a recharge until six weeks later after the first charge. That was much better than I expected. The lay out and feel wasn't much different than my other 10 year old Logitech keyboard that bit the dust. The only improvement I recommend is to extend the auto turnoff illumination time longer. It turns off after 3 seconds. That is annoying when working in low light. There is the option to turn on keys all the time but I prefer the auto turnoff to extend battery life.
One thing to note is that my Logitech MX 700 mouse now has some minor compatibility issues that may be from wireless signal interference between the mouse and keyboard. So if you have an old Logitech wireless mouse you may need to upgrade the mouse as well.
What's great about it: Illuminated keys and rechargeable battery life is very good.
What's not so great: Auto key illumination turnoff is too soon.
