Very hard to adjust to get to the no-leak point.  I think the fact that the headstrap is a single band that splices in two partially in the back is a problem.  If the straps were truly separate from the corner of each eye piece, then it might be easier to adjust to get the right grip on my face.

I can't get a good seal, so they constantly leak.  Not a good goggle for the money.

They are the best fitting goggles I have ever used.  There is no discomfort around the eyes.  They are comfortable after swimming laps for a mile.  Great product.

These goggle are exactly what I was looking for.  I wanted comfort and good visibility for my regular workouts and I couldn't be more pleased.

The field of vision when you are wearing these goggles is excellent. Making them great for triathlons. They don't restrict your vision at all. The only downside to these is that every 4 months or so they seem to spring a pretty bad leak.  That doesn't stop me from buying a new pair though.  I am on my third or fourth pair.

This is the best one I have ever used.  Great seal, no leaks, and very comfortable.  Will buy a couple more pair for spares and would highly recommend.
