A truly perfect keyboard, having passed a Logitech G11 whose backlight beginning to falter, whose shot was too loud, I acquired the Logitech Illuminated Keyboard. Backlight with stunning 3-power modes, very quiet and very flexible button, it takes very little space on the desktop and the wrist rest and comfortable. Negatives: a part of the band of the wrist rest is a little "detached" (already during unpacking) not really a problem though, even wrist rest tends to take quite the dust also because the material is suitable for catch it, but a little bit of anti-static cloth and presto!
