The mask is worth the money, yes it is expensive but it is very well made with soft materials, it doesn't tire even after hours in the water... You just need to adjust it to your measurements and get the right size.

Within a week of purchasing the mask, and with minimal use (5-6 times), the back strap that holds the mask tore, making it essentially useless.

I have had other masks in the past, much cheaper ones, and none of them ever had a torn strap or band.

Such a waste of money.

Two stars, for good visibility and because it didn't let water in while it was working.

Reliable, durable, dazzling, easily adjustable. The only difficult point is the joint between the main body and the air duct, it is difficult to connect!

After 10-15 dives with it, I did not see anything that would make me recommend it, probably an unnecessary invention. I don't think it has such a big difference in visibility (compared to a regular mask) underwater that it's worth carrying something so bulky and heavy.
