Excellent Seller and Product!!!!! T H A N K S

I am a mechanical and design engineer. I originally bought two different transparent snorkel/regulator mouthpieces from two different dealers on Amazon and both had the same problem; they where designed improperly and as a result, fit loosely and leaked. Beyond belief that they could be selling such inferior products, I bought and tested the following four snorkel/regulator transparent mouthpieces from Amazon determined to find some quality transparent snorkel/regulator mouthpieces. Following are my results:Tied for first place and the only two quality transparent mouthpieces that I found out of these four that I ordered:1st place: Herchr (buy)1st place: Zetiling (buy)Note: Both of the above fit nice, tight, properly and, a result, leaked no water. Note: Their appearance is almost the same so there is a chance that both of these products above are made from the same manufacturer.2nd place: Mollytek (do not buy)Note: fit was semi-loose and might prevent some leakage but still not tight enough and, therefore, leaks will most like occur.3rd place: Promate (do not buy)Note: fit was very loose and odds are high it will leak. Too bad too because I had high hopes for this mouthpiece due to its interesting, rounded comfort design.I did not get a chance to buy other transparent mouthpieces because I did this test just to locate and buy some well made transparent mouthpieces for myself. Now that I have found two quality mouthpieces, there is no need for me to test others.One final tip: If the mouthpiece comes with plastic zip ties, DO NOT BUY. A quality snorkel/regulator mouthpiece should require a decent amount of stretching to be able to be installed and uninstalled onto the snorkel/regulator. If you can just push it on and/or pull it off with ease (little resistance), chances are high it was designed improperly and will not be tight enough to prevent water leakage.

Good product

Great value

We took these to Cozumel Mexico diving. The scuba club that we stayed at required you to provide your own mouth piece due to COVID. Worked great on the rented regulators.
