Never had a problem with there rebates, takes 10-12 weeks to get them as do most rebates, but they come in.That looks like a good deal if they actually send out the rebate cards.
Have a 8gig ver of this drive and never lost the cap.Just throw the rubber cap away when you get it. That way you don't waste so much time trying to keep track of it only to lose it in the future.
Other than that annoyance, good stick and Corsair does stick by their warranty.
