||Haven't used it in a game yet, but here's my thoughts so far:
Great quality, though and heavy plastic (doesn't feel cheap).
Looks really cool.
Not too hot due to large openings.
Mesh seems to be of good quality (not tested in game yet).
You don't have to tilt head to look down because of the large openings, making it easy to move around.
Can use glasses underneath.
Easy to adjust.
Fits my big head.
Comfortable padding inside.
You loose some of the sideways view.
When you tighten it to fit your head, the straps get quite long and hang/sticks out which may ruin the slick look, if thats important to you.
I didn't test it with a rifle, so I dont know wheter or not it gets in the way when aiming, but I don't think it should be a big problem. I have tried three other masks, and this is by far the best, both in quality and comfort. A great buy.
