The Logitech Illuminated Keyboard is, apparently, the very best product in a category that is still becoming mainstream. Until recently, backlit keyboards were mainly the preserve of gaming fans and specialists working in dark environments, but Logitech is now trying to bring this functionality to a wider audience.
The usefulness of a having lights behind the keys is fairly self-evident, but whether or not it's a good keyboard itself is another question.
Nice and thin
Once you turn it over, you discover that it's possible to use it either flat, or, by engaging a support at the back, with a gentle slope. What's missing is the opposite--a support at the front, allowing a downward slope--which some recent Microsoft keyboards have featured. While this is certainly hard to get used to, it's actually a more natural position for the hands.

The keys themselves are like those on a laptop: flat, and without much depth. They are all quiet, apart from the space bar which rattles a lot.
The backlighting system it works excellently. The font used for the letters on the keyboard has been updated slightly (and we can't help but think it looks a lot like our own logo), and makes for a strikingly modern look. Every key is always perfectly legible, from bright light, through darker conditions right through to absolute darkness whether the keyboard itself is the only light source.
A button to the top right of the keyboard allows the intensity of the light to be set to any one of four levels, or even turned off entirely.
Three different brightness levels for the backlighting
Although we were initially worried by the first of these keyboards that we tested, which had a very loud space bar, and, as you can hear in this video, noise levels are well under control. We compare it here to one of the quitest keyboards we've ever tested, a Cherry, and a classic Logitech with big deep keys.
Finally, according to your needs, you can change the mappings of the different hotkeys using a tool supplied by Logitech.
