Solid construction, great price


from Orinda, CA, US

Wonderful tool for snorkeling. Compact, well built, and tight closure. I had previous similar type (different vendor) and it lasted 5 years, altho started allowing water in as I begain overstuffing it. Hinge finally broke when I reached its limits! This one feels even more sturdy.


It leaks!


from Auburn, WA, US

If it weren't such an inexpensive item, I would take the time out of my busy schedule to actually return it. It leaks. I have dove with it 6-8 times now, and it has leaked on every dive. No dives have been beyond 80ft, and it is supposed to be rated to 100 ft. Don't waste your money!


Don't put in anything that can't get wet!


from Norcross, GA, US

We have used this several times, but don't put in anything that can't get a little damp. (ie rental car keys with transponders) While it has never filled up with water, some has certainly seeped in. I suspect even a grain of sand on the seal would compromise it a bit.


Perfect size diving case


from Colorado Springs, CO, US

Use the case to hold keys, credit card while diving. 100% waterproof during all dives down to 100'. (Have not done any dives deeper than 100'.) Compact size easy to fit in small pocket. Highly recommend.

JOSEPH C  Leslie, Thanks for the info.
LESLIE R  No it will not. There is one a little bigger thank that one.
JOSEPH C  Alain, Thank you for the info.
Alain R  No, an iPhone would definitely not fit in. Additionally, be aware that up to approx. -20 m above water surface, due to the pressure, the lock releases and water gets into the case.
