This is only compatible with BDM-010 & BDM-020 controllers. The BDM-030 and BDM-04x will be in the next week or so.
These will be available on our site soon as a direct replacement with x4 button pre-soldered on the flex.
This will enable people to restore their expensive SCUF controller back to original condition in the event of breaking the delicate flex cable causing the rear buttons to stop firing or no power to the rear profile button.
