I tried and tried with this mask, it won't stop the water from coming in. Not what you want! It was so tight it started to give me a really bad head ache. How is that enjoyable is that to have a headache while your taking in the sights underwater?
So after repeated tries and a nose full of water I have indeed given up. Maybe I have an odd shaped head, maybe I'm just not fitting it right or maybe it's nothing to do with me at all. All I know is I wouldn't recommend it unless you have time to try.
On a brighter more positive note its a breath of fresh air when you don't have endless amounts of packaging to put in the bin. The mask is certainly packed safety but it's looking after the planet too.
