Apple buys from corsair for 20 bucks, sells it for 180.
Let's be honest though, neither of them are better or worse, it's personal preference. You're not overspending if you're happy with the price you bought it for.
I mean sure, I can buy a different product that performs the same for ~65% of the price, but that doesn't mean somebody that buys that apple product is suddenly 'retarded' for buying that. If they like what they get for the price why should I care?
