My daughter is on the high school swim team. She has been swimming for about 7 years now. We recently moved and she's attending a new high school. When asked what goggles he recommended, the coach opened his file cabinet and handed us a pair of Vanquisher goggles. My daughter tried them at her next practice and came home from school praising these goggles. She wears contacts in the pool and says that no water gets under these googles. She also said that they are very comfortable. I'm back to buy a couple pair for her younger sister.
UPDATE: My youngest (age 14) loves them too, and my girls never agree! 5 stars

I've been using these goggles for a while now. I've tried several other goggles and the fit with the silicone is just right, and very comfortable. I thought that the silcone would wear out, but it's lasted me many swimming sessions and is still airtight (although I have to adjust the straps tigther because the silicone straps are loosening with use). Vision is good but I've had a better view with other goggles. It will also fog up slightly with extended use. Anti-fog drops or spit will fix that up. I've used them to swim in lakes (triathlon) for extended periods with no issues. I've also noticed that Speedo's quality in all of products I've tried (silicone swim caps, swim jammers) is above par. I guess that's why they're the industry leaders. It's a great pair of goggles and Amazon's got a great price on them with free shipping to boot. 4 stars

I have trouble with most swim goggles, because they dig into the bridge of my nose. The Vanquisher model has a higher bridge, but still has a wide field of view. They are quite comfortable, and have really made my swim training a pleasure, rather than a torture ending with an "indented" nose. 5 stars

I used these and I like them. I have a big head, but these still fit! I can see the bottom of the pool with no water leaking into and no fogs. I chose smoky color, so they do not see me, but I can see them. I do not want people to recognize me; when swimming, I am like a hippo bathing after eating full lunch. 5 stars

I bought these goggles for use swimming laps. I wear contact lenses and need the goggles to avoid the hassle of carrying contact lens periphenalia to the gym and to enhance underwater vision. I bought these goggles as they appeared better than bottom rung, but not too pricey. They work perfectly; keeps the water out, fog free. I'd recommend them for other swimmers seeking similar results. If you're really looking for competition goggles, I don't know how these would fare since I haven't used them in that context. 4 stars
