The 5 GHz ultra-slim touch keyboard E9270P is a remarkable product. It appears simple, light, clean and flossy. The aluminum alloy front cover and stainless steel back cover make the keyboard unique. The thinnest part of the body is only 4 mm. An accurate scissor key structure distributes the force evenly over the keyboard surface. With the perfect combination of visual and tactile attributes via acrylic backlights and smart sensor, the backlight brightens up, when your fingers approach, and vibrates slightly as touched; the backlight slowly darkens, when your fingers leave. The whole thing brings an extraordinarily comfortable and very cool experience.
