Product Description

Vengeance K90 Keyboard
The K90's professional-grade brushed aluminum chassis is visually stunning but built for durability..

The Vengeance K90 Gaming Keyboard: Designed for performance gaming

Cherry MX Red mechanical key switches

Cherry MX Red key switches are the best of the best — they provide the sensitivity and low operating force that professional gamers love. Reaction times are ultra-fast and responsive for quicker double and triple taps. The action is predictable and linear unlike lesser gaming keyboards that have a tactile bump or the annoying click of a typist’s keyboard.

18 dedicated, customizable G-Keys

Easily access to your most frequently used macros, presets and key combinations even during the most intense action. You can record up to 54 programmable functions accessible from three separate banks, ideal for grouping macros by function, or access.  Macros can be created on-the-fly, customized, and activated with a single keystroke.

Full key matrix anti-ghosting

Our expertly designed anti-ghosting technology provides flawless control even when you're pressing multiple keys at once.  The K90 has individual switches with dedicated diodes for each switch so every key press results in an input and is 100% ghost free without tradeoff or compromise.

20-key rollover (20KRO) on USB

Typical USB gaming keyboards are limited to the USB standard six-key rollover. The K90 features increased performance with a 20-key rollover implementation on USB at a blazing fast 1ms (1000 reports per second) reporting rate.

Professional-grade brushed aluminum chassis with laser etched keys

The rugged aluminum chassis provides increased durability and stability compared those that are primarily plastic. The stiff suspension chassis and the laser etched keys are made for durability so they won't degrade over time. And the K90 has over 90 LEDs that provide outstanding illumination even in dim light.

Well seeing as nobody else has reviewed this yet- it's high time to provide some honest feedback and let you know the K90's pros / cons.

Put simply - the K90 is an extremely good board! Firstly, ignore all the complete crap you may have read about the 'not all mechanical' switches destroying this board and not making it worth buying - ultimately 99.9% of your keystrokes will be on mechanical, ie - the keys that matter are mechanical. The only change Corsair could have made to improve it would be to make the Insert--Page Down key block mechanical, however in the bigger picture, this is a fairly insignificant downside for the K90.

================ What is good about the K90? ==================

- Build quality is top notch. Strong, hard wearing, very thick cable with solid fitting (you could probably tow a car with it). The keys are raised, which makes them very accessible for cleaning etc.
- Wrist rest is fantastic - soft to touch, hard wearing and rigid. (Coming from someone who doesn't like wrist rests, this is a massive bonus point to the K90)
- The backlighting is good - bright, customisable and permeates well through the majority of keycaps.
- The mechanical Cherry MX Red's take a little bit of getting use to, but they are relatively quiet (in comparison to other Cherry MX's) and are a dream to type on and game with. I can already see myself never going back to rubber dome again.
- Features!!!! Multimedia keys are simple but are all you need, the volume slider is ace. Anti-ghosting means no 'keyboard's fault' excuses when hardcore gaming, the macro keys / record feature is VERY easy to use and change on the fly.

Packaging and contents:

The box, in common with other Corsair products I have tried, comprises minimal packaging and lets the quality of the product speak for itself. This is in sharp contrast to something like Razer's products for example, which are in my opinion, over-packaged in order to try and give the impression of quality. I believe Corsair should be commended for their approach to packaging, in these environmentally conscious times.

All that is in the box, is the keyboard, a warranty card, and a piece of paper telling you to go to Corsair's website to download drivers for the keyboard.

Keyboard Quality:

The keyboard just screams quality, from the brushed aluminium, to the feel of the keys, and the thick braided cable that runs out of the back of it. You truly feel you have purchased a premium product. The plastic areas of the keyboard feel like they are made from a good quality plastic and the coating of the keys with a matt effect black surface works well. Note that the keys on this keyboard are laser etched (unlike the Corsair K60 keyboard) and should be extremely durable. I have only seen one reported incident of the key surfaces wearing out on a couple of the keys and that would seem to be an exceptional case. Please note that not all keys on the keyboard are mechanical - the Function keys, the G Macro keys and the page-up cluster are rubber dome. All other keys and the numpad are mechanical. Whether this will be an issue or not for you will depend on the individual, it is certainly no issue for me. The keyboard also has media keys on it, that include a knurled, aluminium volume knob - a nice touch and not something I have seen elsewhere.

Corsair have built a very solid keyboard. The blue backlighting is fantastic and really shows the keyboard off. The wrist rest is solid and textured with a screw at either end for extra durability. The keyboard itself is mainly mechanical, with Cherry Red MX key switches. It is well laid out with a brushed aluminium backplate and 18 MMO keys, set slighly lower, to the left of the keypad. The 18 MMO keys, the escape key, the F1 - F12 keys and the small bank of keys to the right, which include delete, scroll lock and page up and down etc. are membrane keys.
Most of that is very positive; but there is one drawback with this keyboard. The downloaded software doesn't work, making the MMO keys redundant.

I purchased my keyboard at the end of February and have spent the weeks since that time trying to resolve this issue with Corsair.

Corsair did send me a replacement keyboard but again, when I downloaded and attempted to install the software a second time, it still didn't work.
What annoys me the most is that Corsair will not answer any of my questions regarding when the software problem might be resolved. I even told them that I was prepared to be patient for up to 3 months, as long as they could reassure me that there would be a resolution to this problem within that period. That reassurance was not given.

So; trying to be as objective as possible. If you are not concerned about MMO keys, this is a good keyboard; but if MMO keys are important to you, look elsewhere.
