The POM plate is designed for softest, and most flexible typing experience out of the three available plate materials.
Want to try other plate materials? Try the Aluminum for a higher sound profile or the FR4 that combines flex and sound.
*Disclamier: only Polycarbonate and Aluminum plate comes with screw slots. It is up to the user whether to use them. For other plates, the switches are used to properly fix the PCB and plate to reach ultra flex experiences.
