Keygeek Klein Blue

Instead of using pure UPE and POM, the stem and housing of the Klein Blue switch are made of modified and strengthened UPE and POM; Unlike pure UPE, the strengthened UPE stem is less likely to deform after long term usage; Also, strengthened UPE creates less unwanted noises during typing compared to pure UPE. The strengthened POM housing, on the other hand, brightens up the overall sound profile of the switch. Furthermore, the combination of UPE and POM is known to create the smoothest switches, and the Klein Blue is no exception. Bottom Housing: L4+ Strengthened POM (Thickened bottom housing)
