Great Diving set for children. The product is stable and flexible at the same time. It was massively tested by my daughter saltwater and found to be excellent. The spectacle is dense, has a good field of view and can be adjusted easily. Also the snorkelling is working very well. He has at the bottom of a small valve through which, however, water will not penetrate. A quarter yesterday, I would have to pull off, however, since the adjustable foot straps are very difficult to operate. Children hands create the by no means alone. Sits the fin but then really everything is io Everything is easy to clean and the salt water has left no traces. I will definitely order the next size up if it is present.
