They are cheap and are a danger to the eye's from what I experienced. My eye's were sore the first 5 minutes of using one.
Also, none meet or exceed ANSI Z87 standards from what I found. For the price they want for there best one, I could order a Z87 approved helmet for 65 bucks, but I figured I would check here first for a place to give my business or save a few extra dollars for something I'm seeking for.
So if ya know a local (clinton Twp) reputable place that sells them for 65 bux or less, let me know!
