The part could convince completely in the last holiday while snorkeling !!! As you descend, the automatic closure function is functioning properly and thus no salt water came into the snorkel. If only water is pure run times by accidental lateral descent, could be up and running quickly on the blow-out function. As practically the mounting clip has been found, with a quick grab the snorkel was quickly separated from the mask. Good is also the flexible silicone tubing and the palate mouthpiece, which ensure optimal comfort. The individual components can be separated with a little fumbling of one another, which turned out to be advantageous when cleaning. Conclusion: Good quality / price ratio. Did the snorkel in the color "white" ordered and also a visual "eye-catcher" (even in the event of losing slightly under water to detect) in conjunction with a white mask.
