This mrning I got EXO-700 and saw that a black plate (the one between the helmet and the visor) on one of the sides is loose. Two black, I think plastic, screws came with the helmet. I see a metal small screw in the place in which (I think) there should be one of the screws I've got with the helmet.... I had to rush to work, so did not have enough time to examine it, but the question is.... do I need to assemble something? Is it "by design" or I've got a "lemon"?
