Bought 4 days ago for my 9-year-old daughter. Size S/M. It seems to fit well but it starts leaking water almost immediately, without me being able to adjust it. I don't know if I'm doing something wrong, but what else could it need? Anyone who has something to suggest, please help. It's a no for me!

Strange and different as a mask since it covers the entire face but is watertight and allows the user to breathe underwater. My nephew asked me for it and he didn't take it off his head nor did he complain that it was fogging up.

It's simply useless.
1. It gets foggy. No matter what trick I tried to prevent it from fogging up, unfortunately, you still end up breathing inside it and it fogs up in the first few seconds.
2. It creates instability due to the foggy visibility, as the water it has (which is logical since you use it in the sea) drips inside and it feels like you have presbyopia... resulting in dizziness.
I recommend not buying it, it's really a waste of money, not worth the 45 euros. It's better to get a simple mask for 10 euros to enjoy your time at the sea.
