Amazon product description and accompanying description differently

In the Amazon product description is that the shell is up to 3m Waterproof.
The brief description which is included with the product with no mention that the bag should be waterproof up to 3m.
That's why I bought them to me, however, because I so wanted to go snorkeling.
If the support have an answer, I will adjust the rating subsequently.

Change from 2 to 4 stars.
Reason: Quick response to my question.
1 star deduction due to incomplete accompanying product description / Quick Start Guide.
Even when space is limited on the packaging may be a printed sheet of paper shall be settled.

As soon as I was with the Beachbag in the water, I will extend my review.

Edit: 20/06/2014
Change from 4 to 3 stars.
Reason: The shell is indeed actually waterproof, have thus been under water, every picture that I However, I have made with the smartphone camera blurred.
Although the shell is dry.
When the smartphone is outside of the envelope, the images are sharp again.
I have multiple attempts to change position, make sure that is no air between the camera and cover, and so on.

Since I also want to take snapshots every now and then in the water and I now have dozens of blurry images, I can only recommend the sleeve limited.
