Check overclock.net or reddit or even Linustechtips. There's been TONS of discussion over this keyboard for ages.
Too much, iMO.
I preordered this keyboard and I don't even use it anymore.
Two things turned me off from it (and yes I'm weird and different so don't sue me for not thinking or acting like other people).
1) RGB levels are inconsistent at lower values, to the point of being totally useless. No brightness at all under 25, 25, 25, and 25, 25, 25 to 30, 30, 30 and beyond go from some being off, to some others barely flickering LED's, to some which appear a bit steady right next to the flickering ones. Just completely uneven and worthless. For a keyboard that advertises 16.8 million colors (256x256x256 RGB values), having 10% of them give NO brightness at all and the next 10% be so uneven, one key might be green while the next might be yellow at the same R+B value, is just...something I personally can't accept. Once you get past 100,100,100, it gets much better to actually be decent (keyboard is pure white at 255,255,255), but still below 100, you can see differences in uniformity. I don't know if it's flaky LED's or horrible voltage regulation, but whatever it is, it's bad.
2) Color effects require software to be loaded or they don't work. Unloading Lcore.exe resets the keyboard to light blue unless you end task on it. Only basic wave/ripple patterns will keep playing if you end task on Lcore manually. There's no way to save a static per-key color profile to any sort of onboard memory to keep active at all times or through replugs, without the software active. This is another pet peeve. The Corsair CUE RGB keyboards at least let you save a non dynamic color preset to onboard memory so it's always active without CUE. At least THAT'S better than what Logitech gives, which is nothing except through software.
I like to take my keyboard to bed with me and play with the color animations on my laptop, WITHOUT software, and my Ducky Shine 5 and Year of the Goat let me do that. The Logitech is sitting in its box now waiting for me to either throw it away or give it to someone randomly or throw it outside for a kid to grab.
Besides the atrocious angled keycaps and the LEGENDS ON WASD--NOTE PEOPLE, I USE ESDF TO MOVE AROUND, NOT WASD--STOP INCLUDING SPECIAL LOGOS ON WASD! I *do* LOVE the way the lighting is in the CENTER of the key and only illuminates the legends, without any bleed. That's well done. And the Romer-G key switches are decent if you want a fast actuating switch that's faster than a MX Brown. I give Logitech another +1 on that. But these switches are even more polarizing than MX browns. Did you see the other thread with some of the toxic hate for browns? "Sand in the key?" what the living hell? I'm USING a MX Brown Year of the Goat to type this up, and I love browns, because it tells me when I depress the key (very nice to not press space or shift accidentally in games!) without slowing me down. So I can see people who like Browns also like the Romer-G switch.
Sorry if my complaints about the low voltage level RGB and software makes me a selfish ungrateful jerk or something. I have my own personal needs and desires and that's a problem for me.
