Both my X-vents flew off.
Yes one was at high speed but the other was at a freeway cruise and my bud said he saw it go about 5 miles back.
Just came off...both of em.
My no3 AGV isnt a Xvent but a cheaper version I bought in a clinch.Its a pos.
I never dropped em either.
Im lookin at a Arai this season but I didnt have good luck with the AGVs I have.
Maybe its my head shape.
