Why stem stability matters?

Stem wobble occurs when there is a loose fit between the switch stem and its housing. While a tiny amount is normal, excessive wobble leads to a "cheap" feeling and inconsistent typing experience. Premium switches like Boba U4T or Durock POM focus on tight tolerances to eliminate this.

About Key Wobble Test

High-end keyboards feel "solid". Cheap ones feel "rattly". This is often due to Key Wobble—the side-to-side movement of the keycap while pressing it.

### How to Check 1. **Rest Finger**: Place your finger lightly on a key without pressing it. 2. **Wiggle**: Try to move the keycap North/South and East/West. 3. **Visual Grade**: Compare your movement to our reference animations (Minimal, Average, Poor).

Box Switches (like Kailh Box) usually have much less wobble than standard cross-stem switches.
