Neoseeker posted a review on the Vegeance K90/M90 and K60/M60 keyboard/mouse combos

Corsair introduced their Vengeance series of gaming peripherals just over a year ago, and they have since garnered accolades from critics and consumers alike. In the case of their Vengeance keyboards, Corsair took a fresh approach to the design by using a low-profile aluminum structure for the keyboard along with Cherry MX Red switches and a dedicated button for certain gaming styles. Similarly the mice in the Vengeance series have also been tooled for functionality, as they offer have an optimized profile, customizable buttons and have dedicated buttons for either real-time strategy or first person shooter titles.

The keyboards and mice are broken down into two series, the 60 series which is designed for first person shooters, and the 90 series for RTS games and MMORPGs. Corsair has optimized the different series by including features such as dedicated macro keys, textured FPS movement keys and a sniper button, all of which can prove useful for gamers during actual gameplay.

Like other mechanical keyboards and gaming mice, the Vengeance series doesn’t come cheap. In fact, both the Vengeance keyboards have an MSRP of around $100, while the mice hoover around $60. However the Corsair Vengeance products are not the most expensive on the market in comparison to offerings from other companies such as Cooler Master, Thermaltake, etc.
