Of course, buying into the Unifying line basically limits you to the Logitech brand, but the company consistently earns our favor across its entire line of peripherals, including The Mini-USB plug sticks out less than an inch from any standard USB and can work in conjunction with up to six other Logitech input devices for up to 10 meters away from the source. With USB ports quickly filling up with hardwired peripherals like speakers, mice, and Webcams, we're happy to see that the K750 integrates Logitech's 2.4GHz Unifying USB microreceiver. Though the K750 may appear aesthetically similar to other input devices, two Logitech-specific features distinguish it from the competition: the Unifying Receiver and PerfectStroke typing system. SetPoint also lets you swap specific F-key functions, disable inactive keys, and add more devices to your Unifying Receiver profile.

The keyboard is plug-and-play so all you have to do is plug in the USB receiver to start typing, but you need to download Logitech's SetPoint software (version 6.2) to customize the one-touch F1 to F12 shortcut keys just below the solar panels. We were also surprised to see that no physical manual is included in the box instead another link points you to an online manual available in PDF form. Logitech's effort to push the K750's eco-consciousness shows up at every turn, from the PVC-free chassis to the 100 percent recyclable packaging, and even the decision to include, rather than a CD, a link to the downloadable Solar App that displays exactly how much light is currently filtering through the panels.
