I've done with the guarantee the same experiences, as reported already in the other review. A control knob jumped after only about 30 dives out of the guide. At Canon, I was told that they can not fix it, even though I had paid the repair. After the housing was only 8 months old, I again demand, and tries to get on a goodwill exchange housing. No Chance. But they have informed me in this letter the same, where the nearest dealer is, so I can buy a new housing. Now I can throw away an expensive housing and stand with the camera that I bought specifically for diving since. Never again Canon, What arrogance.
