In some cases, micro-switch or soldering have caused pre-travel of side button. To fix this, we provide optional side click parts to reduce the travel distance. The contact face of this optional part is thicker than normal (+0.5 mm). This optional part is cut off at the end as shown in the picture, so it can be distinguished from the normal one.

    Excellent mouse design, sturdy and great build quality. The SLS printing is amazing and the engineering of the mouse is mind-boggling. A very good purchase.
