The mask is amazing for its value for money. Perfect fit... As soon as I got it, I burned the crystals and it didn't fog up at all... Tips for defogging and to never fog up: When purchasing the mask, burn the crystals with a lighter to remove the silicone film, wipe the crystals with a tissue, and you're good to go... Before diving into the sea, spit on the crystals very well and rinse with saltwater, wet your face well and then wear the mask, and you will never have any problems, it will never fog up.

Excellent and durable mask for children. After 2 summers of use and of course not being rinsed after the sea, the 6-year-olds and 9-year-olds threw it away. The only thing that broke was the elastic that ties behind the head, which is disposable and can be purchased separately. Excellent purchase if you can buy it for around €15
