fixdaily: The base mount section is held on with 2 zip ties and the center portion is held on by the velcro inside and the 2 zip ties that go through the holes on the outer rim of the base mount, The 2 zip ties that I place on the inside next to the velcro, I have just drilled 4 holes on the corner of the velcro to just relief some of the stress on the visor to keep it from cracking. This does require you to drill about 8 holes in the mount alone and 10 holes in your helmet visor so take your time and I think this will work better then the goggle mount at this time,
