This review is for the K70 Lux rgb with cherry MX reds.Corsair makes the best gaming keyboards on the market in my opinion. The K70 Lux series is one of their high end models, the K95 platinum being the flagship model. I'm coming from a K70 with red LED and cherry MX reds (the tramp stamp version, purchased in 2015). I LOVE that keyboard, it's still like new to this day. Fantastic build quality, and with periodic cleaning it still looks outstanding. After 2 years though I thought it was time to upgrade to an RGB keyboard. I don't really care about all the crazy lighting effects and rainbow spirals, but I did want the option to choose any color I want and to change it up from time to time.The lux is basically the revision to the standard K70, with an updated lighting controller and new keycaps with a wider, larger font. I was hesitant about buying this because of the font actually, it didn't look very nice in pictures. I have to say though once I got the lux and saw how much more light the new font lets though, I really appreciated it. I actually think the font looks quite good in person. It's hard to explain, but it looks very bold, but also clean. I've seen it described as "gamer bro" font, but I disagree. I think it looks quite elegant.I was also hesitant because my standard K70 with red LED does not require the CUE software to run, it's plug and play. I'm not a big fan of the CUE software, I found it a nuisance with the m65 pro RGB mouse. When you first plug in the lux rgb, without the software running it defaults to a red color with white on the wasd and arrow keys. Once CUE is installed, it defaults to spiral rainbow. The led colors are super impressive, but that sort of thing is a little much for me.The software has a few built in lighting profiles, and also a ton of community share profiles. The one you see in my pictures is a static rainbow profile someone created. I guess they used to have this profile, but got rid of it in recent CUE versions. I think it looks great, so I've been sticking with it. The software allows you to save static lighting to the device, so I also saved a blue static lighting profile to it. When my computer boots or wakes from sleep, they keyboard is now blue instead of red. Looks great.The new keycaps are really good. They feel a bit more premium than the standard K70 caps, and for some reason they actuate much smoother. I think they are great overall. I also swapped in the textured fps caps as I did on my previous k70, I love the texture and the curves that keep your fingers in place.The brushed aluminum also looks slightly higher end than the standard K70. Overall just a gorgeous keyboard.I tried the mx speed switches in a retail store, and I wasnt a big fan. They felt slightly different, and are much louder than the reds for some reason. Keep that in mind when deciding what switch to get.Edit: Had to request a replacement today. The keyboard started randomly dropping connection, all of the lights would turn off and back on. Also the D key seems to have some sort of issue, it feels like there is a click when actuated and it feels slightly wobbly, and as a result fails to register sometimes. I'm chalking this up to getting unlucky, I still think this is a 5 star product!
