I bought two of these. Both units worked perfectly the first day we used them and we thought they were perfect - so much nicer for snorkeling than a regular diving mask. However after the first day both units leaked around the seals on the face. We could only swim for a couple of minutes before having to empty the water out of the mask. We tried all kinds of things to figure out the issue but never came up with an answer. We did rinse our masks off in fresh water after each use and tried both tightening and loosing the straps but all to no avail. It almost like something in the quality of the plastic seal or straps changed after the first use. This design is a real winner for snorkeling as viewing and breathing are much better than with a regular mask and snorkel. I just hope at some point the seal issue can be addressed.

For years, my wife continually had trouble with masks when snorkeling. Even a very expensive, highly rated mask failed to prevent the leaks and fogging that ruined her snorkeling experiences. Tightening straps to the point of pain and applying copious amounts of anti-fog solutions were to no avail, Then she found this product and decided to try once more.
It fit comfortably, did not leak at all and never fogged!. Finally, after years of frustration, she had found the right mask for her.
I was happy with my mask with its corrective optics lens, but after hearing my wife praising her new mask so highly , I decided to give it a try in the hotel pool. Not only did it fit comfortably, not leak, nor fog, but I could see the bottom of the pool as well, if not better than with my mask with its corrective lens. The next morning, we found the only dealer on the island that carried this brand and model and bought one for me, too. Two weeks of snorkeling later, neither of us ever had to stop to clear our masks of leaking water nor fogging!
It did take a little getting used to the full-face design, but after a few minutes, it felt natural and comfortable. By the end of the day, we didn't experience any jaw fatigue from clenching the mouth piece of our snorkels since there isn't one in this mask. Just breathe normally through your nose, or mouth, or both.
We'll never go back to using conventional masks and snorkels after experiencing this product!

I took a pair of these down to Mexico to try them out for the first time. I've been snorkeling for years and these are BY FAR the best I've used. Water pretty much stays out of your face and breathing without a mouthpiece is great. Snorkel doesn't let water in and I didn't have much of a problem with fogging either. These type masks are becoming very popular where we were (Akumal), as lots of people had them. A great buy, operates as designed. Very happy customer.

Bought this mask for my trip to Jamaica it is amazing love being able to breathe normally underwater and literally see everything. I will never use a regular mask again!! Big thing with me is fog experienced none with this mask. Only issue is today I went out and the mask started leaking I don't know what the problem is I've tried everything but it keeps leaking so it only lasted me 3 days hopefully I just got a bad one.

I am a fan of this full face snorkel mask, why?
I just returned from swimming with sharks in Hawaii, and I was concerned I would not be able to see anything since I am pretty blind and don't wear contact lenses but prescription glasses. Well, I visited my optometrist, got fitted for and purchased contact lenses which I tried on for a week every other hour to try getting used to them. I couldn't get used to them since I have astigmatism, the lenses were only to see far, so anyway. After arriving in Hawaii, I tried the mask in a swimming pool to learn how to use, I tried it without glasses, contacts or anything, and voila!, to my surprise I could see every single tile at the bottom of the pool, just as if I was wearing glasses! And, I could breath normally just as if no mask at all. Needless to say, I went to swim with sharks and used this mask, and I was able to see them all close and far, I am impressed! Oh, and it is super cute looking and got a ton of: hey! Where did you get that! Thank you!
