I bought this mask because of good reviews but was really disapponted. I bet those that gave good reviews, never owned a quality mask. Just out of the package, it smells like cheap plastic. The strap is not very flexible , the plastics that hold the strap look very cheap and brittle. There is a sticker on the lens saying that it does not match the EN16805-2015 standart and can break on impact. It doesn’t seem like there are high standards for the quality. To sum ip - it is just cheap Chinese stuff marketed by a Scandinavian - a success story for him, but rather a fraud to me.
