Swim After nearly three years of use and more than 1000 times go in bathrooms or near the sea, there are few weaknesses to report. Although the swimming goggles completes still, but it needs now nachmale but two attempts until it is properly seated and only after many years.
Plunges into the water, I have never done so. But I have often snorkeled with these glasses up to about 6 feet in depth and made other diving exercises.
The price / performance ratio and the comfortable fit is very good for me and I am completely satisfied with this swimming goggles and will also buy my wife and myself at any time again.
