I can not say anything negative about the function of the snorkel. No unnecessary water while diving in snorkeling and blowing by descent also works flawlessly. What, however, to move me to forgive only three stars is the fact that the mouthpiece in use leaves a pungent taste in your mouth again union that lasts even some time after the end of the dive. Must in my view for a device that will be in no case held in the mouth!
