HMX Lulu Silent

Silent linear switches designed by SULAB, manufactured by HMX. 

This switch feels noticeably different than WS White or Huano Silent. The sound is muted but you feel less of the dampener. It has a very solid bottom-out which is quite rare in silent switches.

According to the designer, the silicone used is softer than previous versions, resulting in a crisp bottom-out feel while achieving better noise cancellation than their previous HMX silent switches
