Tom's Hardware Guide published a review on Corsair K70 LUX RGB Keyboard
A quote from the article:
Corsair's K70 LUX RGB keyboard is an iterative update to the K70 RGB line. Corsair makes a wide variety of computer peripherals, but its range of mechanical keyboards, aimed chiefly at gamers, has gathered a fair amount of attention. The K70 LUX RGB is the successor to the popular K70 and a slightly different version of the K70 RGB. It's available in several layouts and with three different switch types (Cherry MX Blue, Brown, or Red) - the version we have on hand is the US/UK model with Cherry MX Red switches. At $160, it is one of Corsair's more expensive models, topped by the flagship K95 RGB at $190 and a couple of others that run $170.Corsair K70 LUX RGB Keyboard Review @ Toms Hardware
