I understand that this review was sort of necrobumped, but something NEEDS to be said about the RGB MX blue switches.
There is a MASSIVE difference in quality between batches, with older batches being completely abysmal, which led Corsair to suspend production of the original K70 RGB MX Blue, and even with the Lux and Strafe RGB Blues, they only do limited runs, as they can't get enough switches to pass QA.
I have four samples of RGB MX blues so I hope this puts a slamdunk to the topic of "blues are annoying."
Two samples: iKBC F108 RGB MX blues:
The blues are very loud and quite inconsistent, some switches are scratchy, and some have strange, weak clicks, and they do sound a bit...annoying. It definitely gives that "annoying to use for a long time" sound feel.
Ducky Shine 6 RGB MX blue:
Heaven. The switches sound as if they are SILENCED. The clicks are there, crisp but yet muted. It almost feels like a completely different switch. The switches are much more consistent. What's even stranger is, the bottom out sound sounds dampened and quieter, even though there are no O rings installed. It's similar to comparing a YOTG RGB MX Brown to a Shine 4 (or shine 3 or G710+) MX Brown...the YOTG is much quieter.
Ducky Year of the Monkey RGB MX Blue: Similar to Shine 6. Same feel, oddly enough the shine 6 sample seems even more consistent than my YOTM.
I highly suspect Cherry finally upgraded their 20 year old machines and started to improve their MX blue switches finally.
Note:
EXACT same keycaps used on Shine 6 and on iKBC F108 (Ducky floating black ABS DS keycaps).
P.S. My old Ducky Fire 69 with MX greens on the alphanums sound loud but much more clean, sort of like a loud version of the Shine 6, but without the dirty feel of the iKBC, feels more like a typewriter (the sound is closer to an Outemu blue, but more clean; an Outemu blue sounds like the click tab is plastic, while the MX Green/Shine 6 MX blue sounds like the click mechanism is metal).
tl;dr: Before hating MX Blues, either get much older samples (like 2013 or older), or try a Shine 6.
