Best decision I have made regarding scuba diving in a long time. Not only is the mask, Tusa Freedom Ceos M-212 Black Silicone, the best and most comfortable one I have ever owned in my 30+ years of diving I can now read my dive computer easier. Another plus is with this mask I hardly ever get excess water in it and don't have to clear it hardly at all. Highly recommend this mask and the reading lens.
