UPDATE:  Initially gave this 5 stars because of good function.  But after only 9 months, the rubber that seals the goggles against the eyes is cracking and brittle.  I din't expect them to last forever but less than a year is still disappointing.  They have been used fairly heavily I would say.  END OF UPDATE.  Sometimes I hesitate to buy something because it seems too cheap.  These aren't going to last forever but what they do well is keep water out of your eyes and they have flat lenses so your view isn't distorted like with some goggles.  We'll see how long they last.
