I bought a pack of four and tested them out before using them in the water. I put a paper towel in each bag and soaked it in water for 2 hours. The paper towels were all dry when I took them off. A photo may show a small moisture stain, but that was due to a drop of water on the outside when I placed a paper towel over the case. I don't rule out being submerged in water for more than two hours so these cases will be great for my use. The case also fits my Samsung S10+ with Otter Box Commuter Case. I could easily press the side buttons, swipe the screen, and use most buttons. Trying to scroll up the notifications was a bit difficult, but I was able to do it and clear the notifications. I also tested this case on an Iphone 8+ with two different case styles and it had plenty of room. The photo shows one of the iPhones with a case. I can't wait to try the covers on my trip!
