Used these around florida water parks lazy river airboat performed well easy to use just close the clips and your good to go was a little sceptical but was proven wrong did keep a little tissue paper at the bottom and kept an eye for leaks but absolutely dry as a bone have kept for next holiday snorkelling did use to snorkel in discovery cove worked well and photos came out fine👌 great for keeping things safe really good at protecting your phone camera from sand and water so you can take pictures on the beach etc
