I will not use it

I had let myself be guided by the overwhelmingly positive reviews, to buy this snorkel. First of all: he has tightly held and during the dive, no water has penetrated into the snorkel.
3 aspects did not like me but:
1. The snorkel flutters in freediving, which is a disease of many silicone snorkel with a collapsible hose.
2. Much more serious negative I felt, if it jumps into the water with a snorkel from one meter height or more,. By the inertia of the mass of the "float" in the snorkel, closes the above access when you're just on inhalation That was more than once a nasty surprise, because I could not really breathe, but the snorkeling was up to before I was in the water.
3. The silicone mouthpiece is too soft for my, with the result that the residual air in the snorkel when freediving with increasing water depth (even at 2 - 3 meters water depth) is compressed and the tongue is "sucked" by the vacuum in the mouthpiece.

Who uses the snorkel not to freediving, but only for surface snorkeling, which will be so surely satisfy.
