My experience is that Canon does the best job of building underwater housings for their cameras. This one is no exception. All the buttons are in the right place and easy to use with or without gloves on. The case seals easily, but I haven't had it deeper than a pool yet so I can't speak to the function at depth, but my expectation is that it will work as well as any previous Canon housing I have used.
