Very good application on the face, without leaving any room for leakage, however it is not recommended for intense swimming due to the small oxygen capacity in the mask, resulting in insufficient breaths.

I gave it 2 stars because the child plays with it a little, it doesn't fit well, it constantly gets foggy, it also lets in a little water, and it tires you out when breathing compared to traditional ones with a separate respirator. It's not worth it, especially for around 30 euros!

Good for now, but I will judge it better next year. Probably not suitable for children under 10 years old (water enters from the sides because it doesn't make good contact due to head size).
Second year: Very good product. It doesn't fog at all (!) and the kids enjoy it a lot.
