We used this case at Osmo Action in Belize this September. It worked great! It fits well, the buttons are easy to use and there are NO fogging issues! My only complaint is that the little pads they give you to prevent fogging make them sticky, making it difficult to take the camera out after use. Otherwise it was great! In case you're wondering, our dives lasted between an hour and an hour and a half, probably averaging around 60ft, but in depths of up to 80 and shallow waters of up to 20. The water temp was about 81 degrees. Can't tell if fogging occurs at lower or higher temperatures or deeper dives, but where we went it wasn't an issue. I've included some screenshots of the videos we recorded so you can see how clear everything is.
