Conclusion

With the Vengeance K90 MMO, Corsair has a high quality Gaming Keyboard in its portfolio which is able to gather lots of plus points through the use of Cherry MX Red keys. The keys themselves release when their pushed down by two millimeters whereas the entire travel is four millimeter. Furthermore Corsair reduced the amount of force that is needed to push down the keys. Normally CherryMX Red switches release at 50 Gramms of weight, with the Corsair K90 MMO they already release at 45 Gramms of weight. This makes especially typing quite a bit easier and it took almost no time at all until we got used.
We also liked that the front plate has been made of aluminium which really suites the long lasting Cherry MX keys. Corsair also succeeded in deploying an easy to use but still stylish software. Like with the gaming headsets the software has been well structured and you wont waste time searching for the functions you're looking for. 

Regarding the design Corsair combines black keys with an aluminium basis, which we really like. There is also a blue backlight which can be adjusted. In fact even during daylight the blue backlight is well visible and it offers a very nice effect. At night or when it's dark the keyboard looks even better. Another feature we liked is the hand rest. Long gaming or typing sessions become quite a bit more comfortable. 

Last but not least we recommend the Corsair Vengeance K90 MMO to any Gamer who's also using the keyboard for standard office work. We think that this keyboard is a very good compromise of both worlds.

The Corsair Vengeance K90 MMO Gaming Keyboard gets excellent four out of five stars.
