I got this for my Sony Cybershot W-150. Did the tissue test, no leaks. Tested the pouch with the actual camera and took some pictures. It worked PERFECTLY. I even used it for my Flip Video Mino HD 2nd Gen (the company only offers an underwater case for the Ultra, not the Mino) at the pool...guess what...WORKED GREAT!! Of course I had to hold it in place, but managed to capture great underwater film with great clarity. When not underwater, sound clarity was crisp and not muffled at all. I managed to put it in a position so that the black ring was not visible at all. You will hear some pops and crackling in the video from the pouch sticking to the camera, but who cares. If you really wanted professional grade, you'd have paid the hundreds of dollars for the name brand. But if you want one for just casual use this pouch is PERFECT.
And even if it starts springing leaks, it would still be great for the beach -- just to keep the sand off the lenses.
