HJKB Full Face Snorkel Mask, Snorkeling Mask for Adults and Kids with Detachable Camera Mount, 180 Degree Large View Dry Top Set Anti-Fog Anti-Leak

The good - these are well made, don't leak (like other 1st gen top snorkel full-face masks), and work just as described and designed.The bad - a few points -1- the full face (180 degree view) is false. the mask which covers the nose and mouth keeps it from being full face and in the end, these don't offer any greater field of view than a good US Divers silicone mask2 - you have an air filled cavity surrounding your face. When you exhale, you have to do so with enough pressure to blow the air out the mask through the one-way valves. When you inhale, you have to do so hard enough to pull in fresh air. In the end, you're not exhausting all the CO from the mask and any air you breath in is mixed therefore with CO. It's much more work to get air, and I myself feel dizzy after a minute or so.3 - (again) you have an air filled cavity surrounding your face. Snorkling is intended for floating on the surface, and being able to hold your breath and dive down to check something out more closely. Now that you have a big air-filled cavity surrounding your face, it is much (much, much) harder to dive and you have to actually fight to stay submerged - which means you use more oxygen and the thing is hard to breath in as noted above.This is a cool design and the dual snorkel mask really does work as advertised. In the end however, it really doesn't work as well as a good (traditional) mask and snorkel.Sorry to disappoint - I wouldn't buy again...good luck everyone!

The inspired air “twobas” seals are difficult to install into the mask side receptacles. A little saliva on the inner seals helped.The stickers attached to both pipes called for a left socket installation! I tried both ways and the installed equally difficult.BIG BEFF IS THE OUTER SURFACE OF MASK WAS SCUFFED DURING SHIPMENT!The blue mask protector film had been installed on the interior of the mask shield surface?It has a tab attached so it can be removed and placed on the outer surface of the mask!They need to provide a small tube of tube seal lubricant AND plastic polish to remove scuffs on the exterior surface of the mask.(100% sure the plastic will be scuffed again in the future, so why not offer a solution)I believe some of the fogging issues cited are caused by the film remaining on the interior of the mask.Leaking issues may be related to1. Improper sizing2. Not adjusting the straps after mounting3. NOT PUSHING TUBES DEEP ENOUGH FOR CLIPS TO “snap” behind the retaining rings!4. Letting hair get in between face and inner seal!

My mask leaks from the top so I tested it on my boyfriend, who has a broader forehead and larger face. Still leaks from the top. The suction just doesn't stay snug. So be wary of fit and size. Perhaps a size smaller is the way to go.Other than that, it's very comfortable. And the glass doesn't fog. You can breath with both your nose and mouth.

It is very difficult to breath while in the water. It seems like the pressure of the water against the exhaust valve is high enough to cause considerable resistance. Perhaps eliminating the inlet valves will help to solve the problem.

I have a few of the masks with the snorkle at the top, but this one is way better. You can tip the 2 snorkels up giving you more room to have your face in the water. Super comfortable and a very nice design. The straps are adjustable, and it seems to have great suction. I can't wait to hit the springs tomorrow and see what we can find!

Don’t bother with one of these they can be dangerous too. Returned right away.

We bought these for a trip to Fiji! They were a total game changer. My husband usually either doesn't snorkel or only does for a few minutes and gets out and with this mask he used the entire time we had available and wasn't even ready to be done. I love that the valves have the stopper to block waves from coming in.

No problems at all ! Used in Jamaica near an inlet and no problems of suction loss and can see sea creatures clearly. And you can go u see water with no leakage In he tube as well. The husband has a a good size head so it was a perfect size. I
