The first one didn't work with USB ports for microphone and keyboard. The video worked as described. Sent a message to tech support and 3 days later no response. I called Revain and they apologized for the manufacture and sent a replacement two days later. the second worked as it should. Pretty cool for what it does when you have two computers, one for work and one for home, and only have enough space for a monitor and keyboard. So in my case there was a 50/50 chance it would work as advertised and there is no tech support. Good value for money if you don't mind the hassle.
