Review on Premium Quality Universal Waterproof Phone Holder with ARM Band & Lanyard - Best Grade, Water-resistant, Dust-resistant, Snow-resistant Case for iPhone 12 Pro Max, 12 Mini, Galaxy S21 Ultra, S20, OnePlus 8, Pixel 5 by Omar Obong

So I bought two of these for my husband and myself. Used them a few times for little things here and there. Underwater shooting in a cave, beach stuff, water park, rafting. So watch out, they don't swim! I was boating in and out of the river when my friend capsized and I helped her, died laughing, got out of the river and found my phone hadn't survived. There was a diver. I told him about it. He agreed to help. Well he didn't find my phone that day but did the next day when he came back! My phone was fine, everything was fine except for the dead battery! My phone spent a night and a day in a raging river and was fine! Please add a float to them!
