Ergodex DX1 Input Sytem can be used as gamepad, controller for Office applications or image/graphic design, etc. You get a set of keys, some pre-printed stickers, a driver disk, and a platform made of two buttons with lights, a USB cable, and a detachable plastic tray.

The keys can be secured anywhere on the plastic tray, according to your speed, hand size, and playing style. Their positions and assignments can be modified at any time and even after countless times sticking and twisting, the keys will stay tight and release easily.

Movie.

Thanks Paul.
