What is the 20MX Kit?

The 20MX Kit reduces the actuation force required to press the buttons by converting the default Sanwa buttons to mechanical keyboard switches.  It also has increased durability and degrades less overtime.  The DIY option allows the user to self install the switches with the included tools (about a 30-60 minute process).  The installed option means the B0XX will come with switches pre-installed and ready to use.
