i bought this last week and took it out on a ride in light/moderate rain. i was riding for around one hour. to my horror, when i got back, there was moisture both inside the case and on the screen of the iphone. mercifully, my phone doesn't seem to have suffered technical consequences from this (although I have had to replace my protective screen cover on the phone, as the adhesive reacted with the water). In terms of a cradle for the iphone, this works well, and i will continue to use it in dry weather, but please don't buy it thinking it's waterproof.
