USB, 2 adjustable feet, 3 very bright LEDs "Num Lock", "Caps Lock" and "Scroll Lock". I wanted a simple keyboard, cheap, small and ergonomic. - Its size is 47x17cm. - It is perfectly simple. without optional keys except the "Start Windows" button. - 10. correct. the brand you pay. - The keys are not very ergonomic: no sweet but tough and slippery, too squares with sharp edges but curved anyway. too deep strokes therefore noisier but reactive. no wrist rest.
I take off a star for its lack of basic amenities. Microsoft quality test on the duration and intensity of use ... Seriously, cut your nails!
