The Matias Wired Keyboard for Mac is for people who miss Apple's wired USB keyboard. Many people still like the reliability of a traditional USB 2.0 connection and numeric keypad. This keyboard by Matias has all the special Mac functionality you expect on the function keys. Note that this keyboard has a traditional USB connection (USB-A), not a USB-C connection.
This model has a plastic keyframe, and does not have a USB hub, so it's a budget version of our higher end wired aluminum model.
