Corsair K70 Rapidfire, Cherry MX Speed switches, Red Backlit keys, Wired, Anti-Ghosting, USB 2.0, Black/Red is rated 4.7 out of 5 by 3 .

Rated 4 out of 5 by Simms from Lighting quick switches and good backlight options Nice overall build quality despite some key caps being lose in the box on delivery. Not an issue to put them back in the right places. Some symbols are printed in switched positions (the keys are the right way round, they won't fit the wrong way). That took longer to get used to than the rapidfire speed. The keyboard can be used with the lighting off completely. It is also adjustable from the keyboard if you don't have windows or want to install their utility. The utility provides animated light effects but can also update the firmware on the keyboard. Mine needed updating. The USB port is handy for a wireless mouse or game controller receiver, especially as it of course occupies a port on the PC in addition to the keyboard data cable.

Rated 5 out of 5 by ProfMeowMeow from Great Keyboard My first mechanical keyboard, bought this over the Razer Chroma, the speed keys take a bit of time to get used to though.
