"That looks like a $17 lighter plug transmitter in a bigger case with a telescopic antenna."

I sent an email to them and got some PDF's back.
It's a little better than that. But you can get 5/15 watts from China for half the $$.

Why use a wall wart when you could use USB ?
And why not make it on a card that goes inside the computer?
