I've been using this device for two weeks to project my windows computer and it supports 4k at 30hz. I'm not very impressed but I'm satisfied. I thought it would support both 2.4GHz and 5GHz, but this particular model only supports 2.4GHz, which isn't a problem if you have a good Wi-Fi signal. When the device showed up in my Google Home app, I figured I could get rid of the Chromecast, but I had to keep both devices. This device works the same as before but doesn't replace your Chromecast.
