Tl;dr - Stab sliders do sometimes hit the PCB depending on the size of the keycap and how you hit it. I still only think this kind of mod is worth doing if you’re using silenced switches, because otherwise the noise wouldn’t bother me when it happens.
The band aid mod seeks to solve the problem of the stabilizer sliders hitting the PCB, making a tapping sound. By sticking a softer material such as a piece of Band-Aid to the PCB under the stabilizer, this tapping sound is meant to be silenced somewhat.
In this video I will explore whether that problem is real by testing it with the most popular types of stabilizers.
Additionally, I will discuss when I think this mod is and isn’t useful.
