Input:
i got a copy of this mask and start to use it for diving.
the view is perfect and it fits my face well.
the only problem with it is the purge valve which make the equilazation very difficult and a painful task, because when you try to close your nose with your finger the valve will pressure your nose. and over one hour of diving in many depth levels you will end up with big pain.
two of my friend got the same problem.

i got a new mask for me scubapro spectra 2 and it is perfect.
