I really liked this mask. I used it for my open water training, one day in the pool and one day in the water. I did not have issues with it fogging or with it leaking (I only got up to 30 feet in it). However, I did have to return it because I needed a mask that was better at blocking the sun. So, I ended up with a tinted mask. I would recommend this mask if you do not have sensitive eyes, or you do not mind the sun in your eyes between dives.
