Given the size, it is difficult to fit on a very small head or on a head with prominent features. I had reservations about buying it, as my nose is like Obelix's and reading the reviews, I thought it would leak water. In the end, it was okay. Good visibility, less fogging. It has a bit more resistance and you feel like a Mercedes in the pool, but you avoid the swelling of the cheekbones caused by goggles. If you get it, be careful not to put the cap inside the mask (on the forehead).

The silicone does not apply well and water easily gets in. The anti-fog lenses are in name only, in practice they do not have much difference from regular lenses

Unfortunately, the product is of poor quality. Specifically, it has poor application and leaks water. It also becomes blurry. In the end, you are forced to constantly take it off and put it back on. If you tighten the straps, it doesn't leak but it causes pain from the pressure. It is downright unacceptable, 20 euros wasted.

Μπάζει νερά, έχει καλή όραση μέσα στο νερό, αλλά δεν εφαρμόζει καθόλου καλά ούτε σε μένα ούτε στην γυναίκα μου που είμαστε κεφάλες!! :D Χρήση για 3 βουτιές και μετά θέλει άδειασμα νερού που μπαίνει από κάτω στα μάτια!!

Very good application, it does not blur underwater (at least during a reasonable duration of swimming and diving) but it scratches easily. I expected it to be more durable

Unacceptable product. It leaks water, becomes cloudy within 10 seconds, and distorts vision underwater. I wasted 25 euros on this!!!

After using it on my own face and on my son's, it proved to adapt to different faces providing good waterproofing. During use, it did not fog up and has amazing visibility. It seems like a value for money product.
