This keyboard now takes its place in the several other vendors who use all membrane keys and are backlit with 2 or 3 colors. The keys are quite flat, the stroke is short, which is attributable to the technology used scissors. It is similar to the Logitech Illuminated or Enermax Aurora. As a bonus, a special anti-ghosting around the WASD block exists. The volume and lighting control is done by rotary control. Real good (and heavy) keyboard when not the maximum brightness keys much too low and the warning lights were too bright. The Perixx PX-1100 is as a positive example. You can buy them for the price or swirling on a different brand.
