Better hope you don't have an issue with the router or they'll replace it with a refurb. I found out by experience and won't buy an Asus product again.
I had to get a warranty replacement from them. The replacement looked like a brand new unit. Plastic stickies and all. But even if it is a refurb'ed unit, it's been working like a champ so no worries.
This is one hell of a router!
