L2: Summary
Hiearcool Waterproof Phone Pouches receive very positive reviews, confirmed effective for beach trips, water parks, cruises, rain, snorkeling, and dive boats. Users consistently test pouches before use (paper towel + water test) and confirm watertight seals. Key positives: IPX8 rating holds up in real use, fits phones with cases (including OtterBox), adjustable lanyard, 2-pack value, and touchscreen works through the pouch. Limitations: fingerprint reader doesn't work through the pouch; closure can be finicky; touch screen slightly less responsive than bare phone; wallet-style cases won't fit.
