Only what Oberflächenschnorchler!

At first glance, the snorkels makes a very good impression, it is nice to swim with him to the surface and sometimes descend without something to worry about is water in the pipe. If it enters something (which was the case in use near the surface almost never), the blow is very simple.

But: The silicone mouthpiece is so soft that it through the residual air in the snorkel diving with increasing water depth (even at 2 - 3 meters water depth) is compressed and the tongue is "sucked" by the vacuum in the mouthpiece.
Also: 2 times I got in a week after the appearance no air through the snorkel after surfacing something goes not.
Similar criticism I have to snorkel Subgear Fusion Dry or sailor - read FUSION DRY dry snorkel; it is probably due to the type of valve-dry snorkel.

Conclusion: Those who use the snorkel only for surface snorkeling, which will be so surely satisfy.
I complained and returned the snorkel. By the seller DiveXshop (Dream Center Diving GmbH) I got sent to the snorkeling pretty quickly; according to the complaint and the return I have the amount + all postage costs reimbursed; Also on the phone my contact person was very friendly.
