To be fair; this has actually had some work put into it as opposed to the licensed products SteelSeries makes; they just take one of their old models and slap a related graphic on it and call it a day.
So yeah, while Razer's licensed products are pricey as hell, I would still buy them over licensed products from a lot of other brands.
Yes, because it makes so much sense to charge a huge premium for changing the logo and firmware and preloading a professional gamer's settings into a product that's already been built. Oh wait. It doesn't.
Which is why SteelSeries doesn't do that.
QcK M unbranded: $10. QcK M with Warcraft/Diablo/etc: $15. Sensei: $89.99. Sensei Fnatic: $99.99.
Also, you obviously don't own anything from SteelSeries. Otherwise you would damn well know that they don't just "slap a logo" on it. Fnatic has mappings preloaded, MoH has a different firmware, WoW Wireless has preconfigured profiles, list goes on.
