Received today and tested in the sink with an old phone. Works as advertised but neither the case nor the locking mechanism appear to be solid. I'll update after a few months of hiking and swimming. I wish it was a little stronger but I didn't pay much and it's better than the ziploc pack I've used before. I'll put one in my luggage and one in my backpack and see how it goes.
