Review on IDRYBAG Clear Dry Bag: Waterproof Floating Sack for Water Sports, Boating, Kayaking & More - 2L/5L/10L/15L/20L by Will Anderson

Everything is working fine so far. I put my phone and tablet in there along with a few other small items when I go diving. That way I don't have to worry about things getting wet when they get into my gear bag. It seems to seal well if you fold it a few times and tie the small end straps together. I also usually leave some air in the bag so it feels a little under pressure. When knocked off the boat, he floats and prevents water from entering. Overall I'm very happy with it. and for everything else I would get another one. The only thing you might notice is that the packs are a bit smaller than you would expect when you turn them over and seal them. So if you are looking for the right size, choose the next larger one.
