I've purchased two pair of these goggles. The seal is excellent, and the first pair survived four years of heavy use (2007-2011). They are still usable for horsing around but not for laps--the rubber is a bit worn.The second pair (the one being rated here) lasted only 1 year of not-so-heavy use before the part of the goggle that attaches to the nose bridge broke. C'est la vie.I then bought a pair ofSpeedo Vanquisher 2.0 Goggles. They broke the same way after 6 months of light use.At the advice of Speedo customer service, I mailed both defective goggles to Speedo, but several weeks later I have not heard from them. I conclude that Speedo' quality has gone down and that they don't care.UPDATE: after two months, Speedo sent me aSpeedo Vanquisher 2.0 Gogglewith no explanation or anything. I had sent a print-out of my amazon receipt for those. After six months, Speedo sent a second pair, again with no explanation.
