Blue: loud clicky switches with noticeable ping, the only good thing about them is shorter travel.
To everybody who's going to purchase these switches: don't be me :)
These switches fit very tight and are EXTREMELY hard to remove once inserted. It might depend on the keyboard of course, mine is ZSA Moonlander. After searching for a solution I know that I'm not the only one who has this issue.
The normal switch puller just doesn't work. It doesn't press two pins at once and the switch doesn't want to get out no matter how hard I try.
I have similar switches from another manufacturer and they are much, much easier to pull.
If you don't have skills to remove switches by tearing the keyboard down OR if you want to replace your switches in future but don't want to waste your time and damage your keyboard while trying to do this, think twice before buying/installing GTMX switches.
