Microsoft is no longer making the Surface Wireless Keyboard Adapters that the company introduced in September 2013.



From All About Microsoft:

The Surface Wireless Keyboard Adapter -- a thin, cylindrical device which used Bluetooth wireless to connect Surface Type and Touch covers to monitors up to 30 feet away -- is no longer being manufactured.

“Due to a number of factors, we are no longer manufacturing the Surface Wireless Keyboard Adapter," a Microsoft spokesperson confirmed. "We are always evaluating our options and remain committed to helping people be productive with Surface."
