Good luck if you end up with something defective. I purchased an Apple Time Capsule that would lose network connectivity after a couple hours. It took some time to figure out what was going on, so by time I narrowed it down to the router I was past their 15 day limit of caring.
I was told there was nothing they can do even though I hadn't even made the first payment on it. They didn't even suggest any options for what to do with a broken 29 day old, $300 router...just sorry, we can't do anything.
Good luck.
