Bottom line is that these are the best goggles I've ever owned and plan to buy these as long as I can swim laps. They fit perfectly, they don't require to be tight on your face so they're much more comfortable, especially for longer sessions, they don't leak, and the view underwater is excellent. And I find them to look very cool which some may not care about but I do. I only had two small challenges: 1. The scan utilizing the app took a few tries but I bet the app will improve with updates 2. I'm getting a little fogging on the inside lens - nothing terrible but I was hoping they would be 100% fog free.
