As a snorkel - it is great - The strap holder on the side can be uncomfortable against the side of your head over an extended time - it is hard plastic instead of soft latex/silicon
The snorkel has help my swimming in the pool. and I will also enjoy them in the river.and the ocean.
HAVEN'T HAD TIME TO USE IT YET. I AM GOING TO USE IT IN AUGUST ON A CRUISE TO THE WESTERN CARRIBEAN
