This device just works.
In my office, there is the wired version of this product.
That works great as is. The frame is not 100% but it's the best you can get.
I was a bit skeptical when I purchased this wireless version.
And when I plugged it in, there was no question about the quality.
It just works. I have a Macbook Pro, using this device, to have Extended Desktop to my 42'' LG TV.
Plug and play. Plug and go. Call it what you will.
[ Things to Note ]
If the connection is not live before you play the video (whether it's from program or from a web),
you have to do the following:
Make sure the link from computer-to-TV is live.
Change the Sound Output to your TV or whatever your unit is connected to.
Then either  Restart your browser if you're using a browser to watch videos, YouTube, Hulu Plus/Netflix, etc., and pull up the same video again, after the connection is established.
 Use a different browser
 Restart the application you're using to watch your content, e.g. Quicktime, VLC, etc.
Other than that, there are no issues that I've ran into.
I often plug and unplug and the receiver and transmitter have no problem with that.
I had AirParrot and an Apple TV the week before I purchased this.
I returned that Apple TV a week after I purchased this.
This is a much better solution if you want to watch whats on your computer, but extend it onto your TV.
Worth the investment.
