mine is in the mail, ups anyway it takes a while after you do the test to get selected, then get the email you were selected, then you have to accept the terms before they send it out.
I was considering buying a similar router anyway, so if it's free, the more the merrier! If they ask for it back, and I don't send it, what are they going to do? come knock on my door? send me a bill? let them!
