I am a snorkel instructor, DO NOT BUY THESE!! THIS IS A HAZARD AND CAN POSE LIFE THREATENING ISSUES!
i'm a snorkel instructor. i purchased this mask to evaluate the new design from the previous full face mask with the snorkel above the forehead. i don't think its the design, its this specific brand. stay away! take my advice, do not purchase this. If you have already, do not go snorkeling with this mask. i will explain why:
there is a ball like apparatus that is suppose to stop water from getting in the snorkel. if you are snorkeling and this valve gets stuck, it can send you into a panic, panic usually precedes drowning.
i put this mask on my face when i receive it and bob my head back and forth to stimulate the normal motions of snorkeling, on my first bob, the valve was stuck. i had to tap the side of it to get it to go back down, (most persons who will buy this mask wont know that).
i thought then, maybe it will work better in water since its design to: shaking my head....
i think you know the results. It was worst in the water. This is by far the worst full face mask I've used. If these sellers really care about human well being, they will stop selling these. they are a hazard!
