Review on Aqua Sphere Kayenne Goggles Swimming by Alfred Paiz

My son is in Swim club and we bought these based on recommendations from third party websites.The fit was decent and he successfully swam in it for about 2 weeks.As he swims regularly we need grooming after swimming, washed thoroughly in cold fresh water and after every workout and competition dried. We kept them in a case too. This morning tightened the side bolts(?) for practice - after inspecting and trying to put them back in place it was easy to see that the side pieces were quite flimsy plastic and bent out of shape I was able to put everything back together but the goggles fell out during training VERY disappointed My son w was used by happily for 2 years but a cheap speedometer glasses. They finally broke down a few weeks ago, prompting us to try this more expensive option - very disappointed that they didn't last more than a few workouts. We're back to the brand of speedometers.
