Getting used to the black edge, as you so his buddy under water can not see from the corner of his eye. However, I have deliberately opted for a mask with a black border, so as no glare (sun / flashlight) can be carried out from the side ... so everything has advantages and disadvantages :-)
A few tips for the mask:
- Anti-fog: In the evening the mask glasses with commercial toothpaste thick rub (until nothing can be seen through the glasses is) and allow to dry overnight. The next day the dried layer abrubbeln with your fingers. If necessary, 1-2x repeat this process yet
- Spit before diving into the mask (alternatively: anti-fog drops), rinse briefly with water - and then it's off into the depths.
Have Fun!
