Bought this mask 3 years agoi used it on one dive. Ill be honest, its the most amazing thing underwater, ive never seen anything like it. BUT i had to use contacts to use this mask and im one of those people who just cant touch their eyeballs so it would take me an hour to get them in. been collecting dust on my shelf and im doing some spring cleaning. Paid 200$ for it, id like to get $140 for it
