I bought this for my DSC-T10 to be used on a snorkelling trip to Belize, but first used it for a zip lining tour in the rain forest. It slipped out of my pocket on the third zip run. It had fallen 50 feet to the forrest floor but was undamaged. The camera was easy to find even in the dense foliage with its white protective case and yellow float.

When I did take the camera to sea it performed flawlessly. All of the camera funtions were available in their normal position and the back of the case was clear for viewing the camera screen.

The float on the case handle was a good idea, not that I would ever drop it when swimming. The case is surprisingly small and convenient to carry.

I had been concerned about cleaning, maintenance and proper greasing of the o-ring seal but after doing it once it was simple. This is a well designed o-ring and any amount of care will allow it to set properly.

The photos from the reef were beautiful and there wasn't a bit of condensation inside when opening. I did have a touch of a fog problem on my first use as I loaded the camera in humid air because power had been lost at the resort and there was no a/c (and I had no dessicant).
