The one that suprises me the most is the complaint " my port wont lock into position and can turn " well I used a Nik V for 15 years and I dont remember the lens locking on that. Take care of your equipment and take care when diving with it and you wont have a problem.
Since this comment is clearly aimed at me any my recent flood, I feel I have to respond. I take incredibly careful care of my gear. I avoid opening the housing on the boat, whenever possible. In fact I usually close the housing up in my home or hotel room, where I have a clean controlled work environment. I then don't open it up again until the end of the day, when I am back in a safe dry environment. I always put the minimal amount of grease to insure that the seals slide smoothly (which, by the way, is the only reason to use grease at all).
As I have said my port turns EXTREMELY easily. Simply placing the housing onto a camera table is often enough to cause it to turn 10-20 degrees. I have been worrying about this problem since the very first day I picked up the housing. I wrap the port with duct tape specifically to prevent it from accidentally falling off. I have gotten email from a number of other people that have had exactly the same failure. Others say that their housing is tight enough that it doesn't turn without substantial force.
This is a problem that is caused by tolerance stackups. If you are lucky enough to get a "tight" housing, great. You might not think that there is a problem. If, like me, you get one that is "loose" you have the port fall off and a $3000 camera + $1000 lens destroyed. To make it more frustrating, this problem could be solved with a simple, inexpensive, design improvement. How many floods have to occur before it gets fixed?
I am amazed at how complacent people get. Just because you can blame the user for the failure doesn't mean that the design is okay. Imagine if someone sold a car that was prone to having the wheels fall off if you didn't tighten the lug nuts every time you got into the car. Would you blame the driver for being sloppy if the wheel fell off, or the designer?
Sure there are sloppy photographers and people that don't service their gear, but this was a case where I treat the system with kid gloves and it STILL fell apart!
