they're ok...depends what type of play you use 'em for. I love it for woodsball..... I like to get down and dirty and one of the first times i played I was crawling through a thick bush and my head was alll scraped up from the branches ....my smart @$$ was semi bald and had no hat..
went out the next day got me a headshield ...did a sweet camo job now I'm content with crawling through just about anything...
Once again its about your preference.... stock lens isn't too good get thermal lens, its way better. get thermal and a fan and its clear skies from there.
