Review on 🏊 T6 20L Swim Buoy: Waterproof Dry Bag & Swim Safety Float for Ultimate Gear Protection during Boating, Kayaking, Fishing, Rafting, Swimming Training, and Camping by Craig Shah

Initially the buoy worked well but over time the screw cap over the inflation valve became more difficult to close and open. About the third time I used the buoy, I heard a whistle through the valve while sailing. The valve did not close and slowly released all the air. After figuring out what was going on, I screwed the valve very tight to make sure I wasn't losing any extra air. I took a closer look as I reached the shore. Looks like the valve is defective; it must be screwed on tight enough to hold the air so that later (especially with cold hands) it cannot be opened to deflate. In fact, I have to twist so much to close it tightly that I later have to pry it open with my teeth. I don't know if I got some kind of defective buoy or if this is the standard for this brand. It's frustrating that a piece of gear designed even partially to save lives should lose air so quickly.
