The mask works well and fits well, but the lower valve of the snorkel leaks water. I had to buy a new one from a tourist shop on holiday with a vito, which plays brilliantly.
A functional game, even children (7- and 9-year-olds) can now watch what is happening beneath the surface.
Fits well on the heads of our 8 and 12 year old children. I eventually bought 2 sets of these.
