Can my voice to the many ratings under certain conditions and have no comparative figures with other goggles. The view is indeed great, but the glasses clamped very strong and exerts quite strong pressure. After much trial and error but one has become accustomed later. Unfortunately, it is so that the glasses on the eye area was not close to me, despite the strong pressure. When breaststroke and a submersion at every train I always had to raise their glasses and let out the accumulated water to 2 meters 25 tracks. Maybe the initial use is due - tightness but somehow the main feature even before a clear day, anti-fog, whatever. Should the mend with time, I will update the review. Presumably this is individual, depending on head shape and facial movement.
