Works perfectly- just plug and play! Due to the nature of the connection, it will also send audio to the external monitor. You can change this in System Preferences (and, in my case, Premiere preferences). This is a not a fault in the cable- my external monitor does not have speakers or audio out, but your setup might.
I use this in Premiere so I have have my edited video running on the external monitor with my media and timeline on my iMac. It makes my work so much easier, and is only about 20% of the price of Apple's USB-C to HDMI dongle.
