The back lighting is terrific

The LED light still comes through them

If the software is not running or it's connected to another computer the lighting becomes static and the effects will not run

The lighting and appearance of the keys is also much more appealing, in my opinion.

I bought this version because I wanted the blue LED lights

-Amazing typing sound-great color quality-excellent quality materials-fun stock graphics in CUE softwareCons-steep wrist rest (for some)-lack of accessories to make light more vivid (white or reflective back plate)-use of RAM for premium RGB effects-the inability to load and retain stock graphics on the keyboard

Very good keyboard, feels nice especially if you have the red switches and the lighting is superb

The LED lighting is great

I loved it and the lights are nice and bright

Great RGB lighting, fast response times, tactical feel, comfortable to use

The keyboard has nice lighting and the Corsair Utility Engine is rather easy to use once working properly

IT!!!The key caps fit my fingers very well and the key presses never felt so GOOD!The lighting features really make you feel like you can customize the lighting for any mood.*people can share they lighting profiles too

The lighting is great and the Corsair software is easy to use and works great with it to get different effects

Love the RGB lighting and ability to map key colors to application/game functions

I do like that you can go into the settings to change the opacity of the LED lights so that it's not too glaring or distracting

The software allows you to save static lighting to the device, so I also saved a blue static lighting profile to it

(The last picture does not do justice to how red the LED lights are, it is much much more vibrant in person).I got the Cherry MX Red because I've never been a huge fan of the click clack noise while I type, and these have the wonderful feeling of a mechanical keyboard without the obnoxious click clack at all

but like the lighting. pretty happy with the keyboard

Easy to clean design, bright lights, but I don't really like the corsair software

This keyboard has a very nice key feel, high quality body, great font and lighting.

The Blue lights are extremely bright on the brightest setting, but are great in lowlight too because they can be dimmed

The lights do not flicker and are nice and bright

Wonderful light show, nice clicking sound, textured volume wheel, comes with a wrist rest, and it is fully controllable

so I wind up killing the lighting completely.

Corsair has outshined themselves, this was an upgrade from a K60 (non-RGB steel edition) and it kept its signature character and strength while adding in much needed, gorgeous lighting

He especially likes the blue back lighting

The back light is bright even at lowest setting (my personal taste)

The L key doesn't work all of the time any more.

Looking at the key, it appears the plastic "T" is either fractured or broken off
