The Logitech K750 Wireless Solar Keyboard is about as green a mass-marketed keyboard as you'll find. It's powered by a strip of solar panels across the top that reviewers say works even in dim office light, is built PVC-free, and comes in recyclable packaging. Because of these features, it is the winner of a CES 2011 Innovations Award in Computer Peripherals.
But review sites say this unusual piece of hardware is no gimmick; not only does the solar power feature work well, it makes it possible for this keyboard to be knife-thin, relatively light, and free of batteries that need replacement. They praise the long life of the keyboard even in darkness, its typing action (in most cases) and the comfortable design of its widely spaced chiclet-style keys.
We found complete reviews and hands-on testing of the Logitech K750 Wireless Solar Keyboard on a number of sites, including CNET, PCMag.com, TrustedReviews.com, the U.K.'s TechRadar.com, ComputerShopper.com and About.com. Hundreds of user reviews give the keyboard a perfect or near-perfect average on Newegg.com and Amazon.com.
CNET's Justin Yu awards the Logitech K750 Wireless Solar Keyboard an Editors' Choice and 4 out of 5 stars, praising its effective solar powered design, "eco-conscious features" such as PVC-free construction and recyclable packaging, and other extras. There is no software support for MacOS, he notes, though a version of this keyboard (the K750 for Mac) is now available for Apple computers. He also points out the lack of a palm rest.

Natalie Shoemaker praises the Logitech K750 Wireless Solar Keyboard's solar- (and office light-) powered design, the slim form factor, easy plug-and-play installation, configuration software and Unifying receiver. The glossy frame attracts fingerprints, she notes, and she compares the action of the scissor-switch keys to a laptop, saying that is "the last thing that a desktop-class keyboard should feel like." She awards 4 out of 5 stars.

In this undated review, Lisa Johnston of About.com gives the Logitech K750 Wireless Solar Keyboard 4.5 out of 5 stars, finding it easy to plug in and use, slim but strong, and lightweight thanks to its lack of (added) batteries. The glossy finish shows dust easily, she notes. (Note: ConsumerSearch is owned by About.com, but the two don't share an editorial affiliation.)

Matthew Hanson's review of the Logitech K750 Wireless Solar Keyboard compliments its slim design, long battery life -- up to three months in darkness on a full charge -- and Unifying USB receiver (which works with other compatible Logitech devices). It's not ergonomic, and its other features are limited, he notes, awarding 3.5 out of 5 stars.

ComputerShopper.com awards 3.5 out of 5 stars to the Logitech K750 Wireless Solar Keyboard, declaring it Business-Ready and A+ for School designations. The review points out the keyboard's unique solar design, well-spaced chiclet-style keys and Unifying receiver that can be used with multiple Logitech devices at once. On the flip side, the shallow profile won't suit everyone, and there is no wrist rest or backlighting, the site comments.
