Works fine but a few instructions wouldn't hurt. This device is similar to the SCR3500A, replacing the USB Type-A port (which required an adapter for use with my 2017 MacBook Pro) with a USB Type-C port (which is all the new MacBook has) . Upon arrival, however, the device was found to be dead and arrived without instructions. After a product return, I finally found an FAQ that indicated that a new driver was needed. Now everything is in order!
