Seems to be of good quality, but didn't fit me well.
Great product to accompany the cressi maui short fins
Ideal addition to the Cressi Quantum mask
Compliant order, delivered quickly and very well packaged. Invoice in the box. I am very satisfied with my purchase.
Cressi quality!
The big minus is that sometimes that water guard blocks the tube in the middle of breathing.
Easy installation and use. A big improvement compared to the old one, which also has a drain valve.
