Input:
Bought this to use with spearfishing after getting more involved. Works great but took a little bit of time to get used to. I have a beard and a mustache and nose section doesn't leak unless you crunch your face just like any other mask. The reason for 4 stars is that when you dive down, whatever water is in the nose section, drains into the lens and blurs your vision. So far, I haven't had any trouble with fogging but did scrub the inside and outside with toothpaste twice and used lens defogger the first few outings.
