Corsair K70 LUX RGB Product Review

So, you want a mechanical keyboard. Easy, right? Not as easy as you may think. Hopefully I can make that choice just a little bit easier for you today, and tell you why you should get yourself a Corsair K70 LUX RGB.

This review includes no paid promotion and is the sole opinion of the author.

I’ve had my Corsair K70 LUX RGB for about five months now, and while it isn’t perfect, it’s still a highly functional, stylish, and fun to use peripheral that I’m glad to have on my desk each day. But let’s not mess around – it’s $160 at full MSRP, and around $120 or $130 when it’s on sale. So what do you get for that mighty high price tag, and more importantly, is it all worth it?

  • Cherry MX Blue, Red, Brown or Silent switches
  • USB passthrough
  • Detachable palm rest
  • Media keys
  • Full range customizable RGB back lighting
  • CUE Software

Firstly, let’s talk about the switches. It comes in Cherry MX Blue, Red, Brown, or Silent. This choice effects the feel and sound the keys make when pressed; mine has Cherry MX Blue switches, which produce a very audible ‘click’ on every keypress, and require marginally more pressure to actuate. The clicking could definitely get on someone’s nerves after a while, but for me personally, I find it helps me type with fewer mistakes as I can hear as well as feel when I misclick a key.

But, if you don’t like a loud, clicky key, there’s three other options of variable loudness and tactile response. Red is louder than silent, and Brown is louder than Red.

How about the other physical components? There’s a single USB passthrough on the back end of the keyboard that essentially makes up for the USB slot the keyboard itself takes up on your PC. I like to plug my mouse into that slot, as the cable on it isn’t very long, and its less of a stretch to throughput it right into the K70. Highly convenient, if not a bit situational.

As someone who has had and still has tendonitis, I am a big fan of the palm rest. It’s just enough to comfortably lay the bottom of your hand on as you go, alleviating the ‘hover hand’ pain that I used to get all the time while I was fluffing up my old English papers. And yes, it is detachable, so if you don’t need it or don’t have the desk real astate, no problem.

The media keys are in the form of an audio roller, stop key, pause/play key, and skip forwards and backwards keys. While I haven’t made massive use of the latter four, I almost exclusively use the audio roller for adjustments on the fly. It’s located on the top right, away from other keys to prevent misclicks, and the buttery smooth action scrolls in that sweet spot between tortoise and hare.

So, what’s this about the RGB? Well, every single key has LED backlighting. Yes, every last one. And with the Corsair Utility Engine software, or CUE, you can customize every single LED. They don’t just have to be static colors either, there are preset animated cascades of color, and fully programmable sets to truly make each custom profile unique, and yours.

CUE is easy to learn, but admittedly hard to master. Not impossible, but if you’re looking to put on some really crazy light shows, a Google search or two might be required. The lights can be a bit dazzling at night when all the lights are off, but of course, you can always turn down the luminosity.

That’s a lot to take in; let’s simplify.

+++ Highly customizable
+++ Easy to use
++ Sturdy build quality
+ Simple to disassemble for cleaning (Includes key removal tool)

Middle ground:
• Media keys, if you use them
• Palm rest, if you use it
• USB passthrough, if you need the real estate

The true downfall of this brilliant piece of hardware is the cost. You absolutely get what you pay for, but it is, without a doubt, a bit steep. If you’re on the fence about the Corsair K70 LUX RGB, I would say to pull the trigger. You won’t be disappointed. Even typing this sentence on this baby right now feels great – but then again, I do love myself a loud, clicky key.

Thanks very much for your time. If pulling that trigger on this lovely keyboard is on your schedule, links are down below – and as always, stay up to date with me and my stuff over on Twitter and YouTube.
