Even though they are advertised as being Kid & nuclear bomb proof, I think the talcum powder digging dust found it's way onto the sealing gasket as the door is opened a lot.. LESS than a pinhole sized failure destroys the watertight integrity..

I interupted morning breakfast for some of the locals..
I WILLNOT be needing the waterproof feature at THIS year's DF
