I totally disagree. The Kraken diving case is exceptional. I did 20+ dives with it in Micronesia this year and the photos are about as good as anyone is going to get without a DSLR. In fact, I was more limited by my lighting than by the camera.

It's also huge to have a screen as big as the phone's, and being able to slip the whole rig into my thigh pocket meant I took it on every dive, not just camera specific ones. I can't imagine a better setup for me.

Edit: You mentioned video. The Paralenz is a much better diving camera than a GoPro. It has a tubular form factor, making it easy to attach to a mask strap. It also is natively pressure resistant and can add depth numbers to your video, GoPros require a case. Here's a dive filmed with my Paralenz: https://m.youtube.com/watch?v=C1MEynCKlhk
