I purchased this housing to go with my S400 for a trip to the Great Barrier Reef. This was the first time I had used an underwater housing. My background: I have been diving for 12 years. Typically in diving - and especially when assembling equipment, you apply a liberal amount of silicone grease. Not too much, but plenty. With this housing, this method will cause leaks. However, if you use just a touch and evenly coat the O-ring with it until the O-ring is shiny - and make sure that there are no areas where you can actually see the silicon, only the shiny coating you shouldn't have a problem with leaks.
