I have tested it and here is what I found :
This usb wifi adapter is a pretty simple unit that includes the adapter and an antenna. It is a dual channel adapter so it works with both 2.4 and 5GHz network. In my test 2.4GHz was a bit slower and that is normal due to more interference on 2.4GHz channel like microwave and nabors wifis. But 5GHz was excellent. It comes with a driver on CD which I did not use because windows 10 detects it automatically and there was no need for installation. Plug and play. The range and speed was normal in this class.
