I've used it for about 6 months. I have a hard time finding glasses/goggles that fit properly. The mask is more comfortable than having to make goggles extra tight, plus it doesn't leave rings around my eyes. It's now starting to wear out and is leaking a little. As far as extra field of vision, I don't really notice it that much. They are geeky looking and I suppose a bit more of a drag in the water, but they are comfortable and wouldn't hurt as bad as goggles if you ever get kicked.

easier to tighten also.

I use them. Love them. Easier fit on my (narrow) face than any goggles I've ever tried. No pinching on the nose bridge, and WIDE field of view.

Yes they are dorky looking and my friends laugh at me but im not a fish so I need all the help I can get. I feel more comfortable in open water with the extra vision I get from them.
I only wear them in open water though.
