Well I just set it up just to see if it works. And it seems to work decently well at the basics to start. It looks like its transmitting at the right resolution, and since I have a tuner hooked up already and I am just sending the feed to the laptop, I noticed there is a 5 second lag. Although, it shouldn't be an issue if it doesn't past through a cable box and you have to control the cable box with another remote.
The sale for the adapter for 59.99 expired already, but as of now it looks to be a good product. I will be testing it out tommorow a little more indepth, but it looks good to start.
