I have a DryCase and at first was a little skeptical. So skeptical that I did my own testimonial with it. I put post-it notes into the case, vacuum-sealed it, and fully submerged it under water for a few hours. It completely worked, and now I use it every time I'm at the beach with my iPhone. It's a perfect way to take pictures, keep sand from scratching the phone, and of course, to keep water away from the phone. I LOVE IT! Such a great, innovative product. I completely suggest you trying one out.
