We just finished a week long trip where we used the snorkels for 2-3 hours every day. They are good quality and do the job perfectly. For this price, they are a great deal!
Bought last minute online for our holiday for my two boys, 14 & 15. Adjustable elastic strap, lasted 2 weeks of solid use and will be used for our next holiday.
All the family has now this mask with different colours. Does not get stuck in the hair and super easy to adjust. Very good quality / price.
