Know before you buy
These dampeners are designed specifically for Cherry MX style stems. They will fit most mechanical keyboards that use the standard cross-shaped stem, but they are not compatible with low-profile switches or non-MX style stems.
The 40A hardness provides a noticeable cushion at the bottom of the keystroke, which can reduce finger fatigue during long typing sessions. Because they are 1.5mm thick, you will experience a slightly shorter travel distance before the key bottoms out.
No, they do not make a keyboard silent. They specifically dampen the 'clack' sound caused by the keycap hitting the switch housing, but they do not affect the internal click or tactile sound of the switch itself.
Installation is straightforward. You simply need to remove your keycaps using a puller and slide one O-ring onto the stem of each keycap before pressing the cap back onto the switch.
A 40A hardness rating is considered a 'soft' to 'medium' durometer, offering a balance between effective noise reduction and a comfortable, cushioned landing. It is generally preferred by typists who want to soften the impact without making the keys feel mushy.
