Getting 4 for the price of one from another brand is an amazing value! Tested all to ensure they would remain waterproof for devices put inside and they all passed the test. Great for when traveling or taking a long bath, just enough protection to feel okay with bringing your device along.
Note on testing: Always test with something you can visually see get wet inside, we usually do lined paper with something written across, the lines will always bleed. And put something small inside to help create the space that the item would take up (We usually use a couple small stones, which also helps keep the pouch held underwater during the test) Noting whatever you put in might get wet as you pull it back out if you haven't properly dried off the pouch!
Note on the pouches: I always figured it was assumed but I had a family member complain - so just a reminder to anyone else shopping that you can't actively "touch the screen" when underwater. So, its not possible to click the screen to take photos. My fix is to take an underwater video, you can start just before you go under & end once you come up - then your options are to re-watch and screenshot, or use an editing program to grab an individual frame for your photos!
