A very good product! We used it for the first time today. No water gets inside and it was convenient on the face with the soft silicone on the inside. We got the small/medium size and it fits our 9-year-old child as well as us, the parents. As adults, we might need a large/extra large because the chin needs to fit inside (not that it doesn't fit us, it's fine for us). It covers from the deepest point above the bridge of the nose to the chin and it works great for us, but a larger size might be a bit more comfortable. However, for starters and for the enjoyment of our child, it's perfect. I believe it would be perfect for people with small faces in general. It is quite convenient and you can see everything inside, especially in beaches with clearer bottoms. I will update in the future for any changes, but I recommend it, it seems good to me.
