This mask is great. The lenses really help in lowlight conditions giving sharp images and are just as good in sunlight. The seal around the mask is so good when it comes to taking it off theres real suction there. No more rings around the eyes. The size may put some people off but if your swimming in low temperatures (i swam in 8 degrees) you cant feel the cold through the mask. A great benefit. As for steaming up I admit I coated them with an anti misting solution before I used them.
