Query: Feels heavy.

I just received and needs a couple more clicks on my head to fit correct. And if I try to turn dial to tighten, the release is on top of dial and I keep pressing it and it gets loose again. I dont know why they designed it with points on the dial. It starts to hurt my thumb if I try to tighten. I bought this cause the light weight but sticker on helmet says 298 g the description says 255. This sucks..
