KUYOU Full Face Snorkel Mask with Latest Dry Top Breathing System, Panoramic Wide View Snorkeling Gear Mask with Camera Mount, Anti-Leak& Anti-Fog Scuba Diving Mask for Adults and Kids

what a great mask! bought for an upcoming trip to Mexico and it is so much better than a two piece mask and has such a great seal I can wear my contacts!!!!

Missed my opportunity to return for larger size to see if mask was just too small., but it had other flaws The mask leaked the second I entered the water no matter how tight it was. Also if you breathe to heavy the ball valve closes, and you can't breathe. When you go under water the ball valve stays open allowing water to enter mouth, and with no purge to expel water can cause you to choke.

Excellent

I really wanted this to work for me. Took it to Puerto Rico and it just didn't work for me. Maybe it was my light scruff of a beard. The anti fog system works great! It just kept filling up with water. I tightened the straps to the point of being uncomfortable and it worked a little better but it just kept filling up with water. I bought the large but it still feels like its way too small.

Bought these for my husband and myself. Wanted to try the full mask. At this price it was worth a try. Husband has a beard so he could not get a good enough seal to keep the water out. I actually had a good experience with the seal but found breathing is a bit restricted. I was not able to get a full breath without working hard for it. If you have asthma this may not be the best choice.

Muy buen snorkel. Su visión es muy clara y hace que la respiración sea más fácil.

My kids enjoyed to swim with them.

purchased 2 of these ... one in a medium and one in a large - there was no visible way to see which was which - and there was really no differences in the sizes, that I could feel. Got them to the beach with us and tested them in the pool first ... could not get them to NOT leak - its like they didn't have enough cushion near the eyes to form to the face to create the seal. we even put them on SOOO tight it hurt and they still leaked.I have owned another type of these kinds of goggles and they were great but they dry rotted after 4 years - so we know what we are doing with them - so its not lack of knowledge of how to use / fit them.I hate dealing with returns and stuff, so we just took this at a loss and left them at the condo (VRBO) for future users to try and figure out.
