serious downsides:
you only get one shot at installing the damn thing in your visor. seriously. trying to rip it off because it's crooked is one toothy mission.

Easy way to fix that is to trace the insert with baking paper, put that on the outside of the helmet make sure you allow for the lid closing once you got it right take the visor off the helmet, apply the insert on the inside done Worked for my anti fog insert anyway!

I've got a progrip antifog with a light tint and it works great. No fog and takes the glare off well. Doesn't work well with sunglasses underneath in a tunnel though but small sacrifice.
