Gateron G Pro Switch Set
Awesome quality, good packaging.
The black keys are a bit "heavier" from the red which makes them perfect for typing, if you want a linear and not tactile feel.
Typos and typing feeling is a lot better with them compared to the reds (reds are awesome for gaming but lead to potentially increased typos due to how "light" feel they have)
I use these as part of a mod to my k6. Worked wonderfully. And the case they’re delivered in works nicely as a line station.
What I love about this keyboard how good the keys feel when you type on them (browns). They aren’t really quiet but that is okay in my house. The lighting options are wonderful where I can cycle through the different patterns I want.
