MOUNTAIN is an accessories OEM that makes its own "premium" switches. Three kinds of these can be used with its latest Everest-series keyboard - however, they can also be interchanged with Cherry MXs for improved flexibility in customization. The new peripheral is of the 60% category, yet has an optional numberpad that can click into it at either side.
