The Microsoft Surface ergonomic keyboard, featuring Bluetooth 4.0 wireless connectivity, is designed to work with all Windows 10-compatible devices. Microsoft rethought keyboard design by splitting the space bar and the surface in half. As a result, your hands will rest naturally on either side of the slope. The keyboard's natural sloping surface, combined with a soft Alcantara palm rest, enhances comfort, productivity, and typing speed. The keyboard requires two AAA alkaline batteries which last up to 12 months at a time.
