As written in the subject, I can not understand the reviews. Of good workmanship and complete water resistance was talk. And the company Cressi this guarantees even on your site. I can not confirm anything. The processing of the product at that price is deficient, the rubber edges at various points of the glasses poorly finished. Rubber processed frayed. The repackaging cheap. But the most important was to me the water resistance. Ordered, pleased, disappointed! That way I can describe it. The spectacle does not deliver what it promises. Continuously water in the glasses. Various settings tasted. Nothing helped! The glasses I have returned. Too bad. Man can not go here ever after the reviews halt. Try it yourself is important. Nice that I (very rare that I'm doing) could give the product without problems back and I get the money back without hesitation. Amazon was great, fast shipment. Thanks Amazon. But this review refers to the product and that's simple: Bad!
