The glasses suits me perfectly. It closes off completely waterproof and suppressed not present unpleasant. That exactly I expect from a good spectacle. I have already used a lot more expensive, especially Aqua shpere. They were at the beginning, although all good, but after one year they had passed over, as more water was pure.
Now, one year is not yet deal with these glasses. Should deteriorate the water resistance, I'll correct this review. At the moment, these glasses - especially at this reasonable price - for me a real top recommendation.
