Have done 30 jumps on mine in the past week and couldn´t be happier. Fits perfectly, took 2 jumps to set up and im away. The only pain with the FFX is if you want to take it out after every jump. I have a low profile dream-optics lens on it but i think i could have got away with a normal one as it sits back in the helmet but doesn´t show the helmet in shot, if that makes sense. Although its a pain in the rear waiting for your helmets i think its well worth the wait.
Have fun.
