Aogek USB Type C Kit, Type C to USB 3.0 Adapter (2 PCS), for Apple New MacBook 12'', Chromebook Pixel, Nexus 6P, Nexus 5x, Nokia N1, One Plus 2 and Other Devices (Gray)

These work perfectly. Haven't tested transfer speed, but for my Logitech mouse M510 worked flawlessly.Con: Bear in mind that for the MacBook Pro 2016, this will block the other USB type C port, which ultimately made me buy something else.

Awesome high quality adapters! Thank you!
