if you can dive deeper than 15', you would need to clear, which requires you to pinch your nose. They might be nice for beginners, but with caution like Mike says
When I snorkel I am constantly going down 15-30 feet and sometimes deeper which requires constant equalizing (popping ears). Maybe I'm wrong but it doesn't seem like that would be easy with these masks. I can see the appeal if you stay on the surface or just go down a few feet.
