I completely disagree.
Unlike many gaming brands. Cooler Master is doing an admirable job of offering products that are not just "gaming branded" but are also a good quality. It is no coincidence that so many people here have been repping their Quickfire Rapid as one of the best bang for buck mechanical keyboards. It was Costar made and of comparable quality to well known and respected brands like Filco. Compared to the other "gaming brands" I would even go as far as to say that when it comes to keyboards, they have the best trackrecord. Their other peripherals, such as their mice, offer a comparable quality/performance for the price.
Additionally, if the product is good, the brand does not matter (other than for customer service when needed). It makes no sense to rely too much on brand names. Especially in consumer electronics. Nearly every brand has some good and some bad products. It is more useful to get some feedback about the specific product you are interested in, instead of believing in brand names. It is funny that you should mention Corsair, who has had for more serious problems in every generation of their mechanical keyboard (LEDs dying, for example), and in my opinion have done a far worse job in their peripherals in terms of performance, despite their popularity. And it does make sense to look at their peripherals, and not random other products that fall under the same brand but are designed, assembled, outsourced, produced in different parts of the world by different people.
Finally, the price is a tad high given that it has ABS keycaps and does not do too much extra, and it has to compete with for example the realforce keyboards. On the other hand, the price is comparable to that of almost any Topre keyboard out there. You pay a slight premium for the novelty of MX keycaps on a topre board. Does not seem too odd. That said, for the price, I would personally go for the Realforce. But that has more to do with how much I like the Realforce's than my dislike for CM.
