Thanks Ccieurzo and Blissed. Burring doesn't bother me; can just sand it off. Thought it was missing a gasket or something. Secondary, interesting story: Revzilla has a couple of E1s on sale for $299 which i thought was a good deal on these. They only have sizes XS and S available at that price. For anyone ordering this plus an M or L liner ($50) like i did; the M liner is actually thicker than the S liner that comes with the helmet. That is because apparently even though the shell is the same, the EPS is Thinner on the larger sizes so they counter that by making the liners thicker. So if you are thinking of buying the S with a larger liner, that's a no go. Per standard measurements i am an L, sometimes M depending on brand. But i always prefer to get one size down, suffer for 3 weeks and then the helmet will mold perfectly to my head as it takes shape and expands. For the last 6 years i've had an Arai Corsair V that i got at size S. Torture for 3 weeks, but after that is like a second skin. Size S on the E1 feels slightly larger than my S Corsair when brand new, so i think it will mold just fine. Mini review based on wearing it all day yesterday: I wish the ear pockets were larger. Added my old Sena SMH10 speakers and the padding hugs the ears (with or without the speakers). I prefer bigger space there. Weight; it is not light. The head liner (for forehead and crown) is a larger diameter than the interior bowl. So it has to fold in two places. It tends to fold/create two ridges on the two sides of the forehead: frontal bone? (high on the forehead, above the outer edge of the eye). These dig in. Will have to pull the head liner to force the folds to happen in the back of the head and velcro/double tape them there. So far these are my 3 gripes with it.
