Backlighting

The backlighting of the Raptor K40 is by far its most notable feature. There are many illuminated keyboards available today but you are typically stuck with a single color, depending on which product you purchase. The Raptor K40 has multiple LED lights installed, allowing it to change colors and even mix colors. Corsair claims that there are 16.8 million possible colors and the software truly allows for 16.58 million combinations; however, this reminded us of the following popular picture:

Although this picture is wrong in a number of ways, it depicts a simple truth: the number that a human can differentiate from one side of the visible wavelength to the other is between five and twenty colors. Females can usually differentiate more colors than males, although not to the level that the above picture depicts. The keyboard does allow you to select from millions of combinations, but most people will never care to choose a color outside the eight basic color settings provided by the software.

Although the ability to change the color of the backlighting is definitely nice, having >16 million colors to choose from is quite a bit of an overstatement. In addition, we should mention that you cannot program the color of individual keys. By changing the color in the software, the backlighting of the entire keyboard is changed. Per-key programming (both lighting and function) is a feature that Corsair will introduce in their new MX RGB mechanical keyboards, which are planned for a release in mid-2014.

Final Words

The Raptor K40 is an interesting product, with Corsair trying to bridge the gap between typical keyboards and expensive high-performance mechanical keyboards. True enough, the Raptor K40 is a very good product and with many notable features, and some users will even prefer good rubber dome keys to mechanical switches. Corsair also provides useful items like dedicated multimedia keys, the six programmable macro "G keys", and the on-board profile storage memory.

However, the most notable feature of the Raptor K40 by far is the customizable backlighting, offering the ability to select virtually any color of the visible spectrum that you want. It may be limited to a single color for the entire board at a given time, but the ability to change the color of the backlighting is somewhat unique (though several laptops have had this ability for years, e.g. Alienware, MSI, and Clevo all have RGB backlit keyboards). We could say that the Raptor K40 is the precursor, a portent of sorts, of the upcoming Cherry MX RGB keyboards that Corsair is currently working on.

As far as quality goes, our feelings are mixed. On one hand, the Raptor K40 is a well made keyboard. Even though the rubber dome keys are lacking in terms of texture, they are firm and consistent across the entire board. There was no discernable wobble in the keys and the larger keys retain their linearity even when pressed near their edges. On the other hand, if you have ever owned or seen a Vengeance K60/K70, the Raptor K40 feels like a cheap imitation. It's not that the Raptor K40 is bad; it is better than the average keyboard but it just cannot compare to the feel and quality of the Vengeance series.

Of course, the Vengeance series keyboards are significantly more expensive, but with a retail price of $79.99 the Raptor K40 is really pushing the limites of "value for money". The Vengeance K70 retails for $129.99, and $50 is a substantial difference; however, a mechanical keyboard with an aluminum frame is on an entirely different level. That said, quite a few gamers tend to prefer non-mechanical switches, whereas typists (like most of our staff of writers) would much rather use a mechanical keyboard. Or if you really want to live on the edge, you could try making the switch to an ergonomic mechanical keyboard, but that's not a step — or a purchase — to be taken lightly.

In summary, we would recommend the Raptor K40 to advanced users and gamers who want a "better-than-average" keyboard. If you've never used — or do not care for — mechanical key switches, the Raptor K40 is a good alternative. You also get RGB backlighting, which we won't see with Cherry MX switches for at least a few more months. However, if you are the kind of person that wants a keyboard "for life" and you're not afraid of pushing the budget a little, we strongly recommend spending more for a premium product with mechanical key switches, as the difference in terms of feel and quality is rather substantial.

    I have two different mechanical keyboards, and I've never even paid the same amount as this keyboard for them. I'd much rather get a barebones mechanical keyboard than a full featured but mushy keyboard. At the end of the day the point of a keyboard is to hit the keys, and rubber domes don't do a very good job at that. Reply

    Same here, would never get or recommend something like this. With great mechanical ones going for ~$60 (Looking at Coolermaster, but not Rosewill) there's just no point in these mushy ones for me. Reply

    Whats wrong with the Rosewill's? I have two of the RK-9000's, one blue for work, browns for gaming at home, and they're wonderful.

    No gimmicky features, full NKRO, and HEAVY. Sounds like a wonderful recipe to me

    Ain't a thing wrong with the Rosewill mechanical keyboards. I've got an RK-9100 MX Blue (blue backlighting too) and it is fantastic. I got it on sale so I paid about $85-90 for it. Money well spent. I love the clickity clack. Reply

    There are MANY complaints on Newegg about the Rosewill Mechanical keyboards. They seem to have a mini-USB connection on them, and it gets difficult to keep the keyboard plugged in.

    Had there only been a few of these, I might have purchased one, but there are more than a few, and I really don't like to return things, especially when some of those people have stated that because the problems set in after 30 days use, Newegg was not helpful whatsoever, and Rosewill was difficult to deal with.

    Yeah, no kidding. There's clearly a market for boards in between bottom of the line $12 throw-aways and the expensive mechanicals, but an $80 rubber domer isn't anywhere near that. That's more then some mechanicals! Reply

    Gaming with a mech keyboard is often considered to be very awkward (I share that view). Typing with a loud and clicky keyboard always feels silly (especially if you're not some shut-in and have others in your household).

    Oh and mech keyboards usually hold minimal extra features yet present manufacturers with amazing margins.

    Great deal for us consumers all in all.

    Not all microswitched keyboards click.
    And I doubt the profit margins on microswitched keyboards are that much larger than their rubber-domed brethren. I'd wager the situation is actually the opposite in most cases, just because materials and assembly costs are so insanely low for a rubber-dome keyboard.

    Right, there are people who will want something like this, but why the hell is it $80? It's entirely made of plastic, macro keys are par for the course, and there's no mention of NKey. Something like this would probably be worth $40 or maybe $50 if you really wanted the customizable backlighting. Reply
