My experiences with the salt water at the last holiday with snorkeling opportunity, has led me to buy this snorkel and test. Again and again annoyed by splashing and waves, quickly passed me the mood on snorkeling. That's over now. Just back from the Red Sea, I can report: it works! Not a drop of water - even when diving - came to my mouth. Even friends of mine have tried it and so it was that the snorkeling in Egypt was because he was bought to me on the spot, when I left. Before my next snorkeling vacation I get me definitely a new one. I'm excited.
