Bill,
Glad to know at least a few people who seem to have sound judgment have tried it. Was being to think I was freak or something!
The space size is something I have wondered too. The middle ear space doesn’t seem very large on the diagrams. The sinuses seem larger. The fact I could still breath through the nose is interesting too, because it suggest that my sinuses where not totally filled. Also the fact that I was able to drain a large amount of fluid out afterwards suggest that I didn’t accomplish the draining of the mask by swallowing the fluid.
I do have a very low volume mask. It is a superochio with the top inside skirt cut out so it fits closer to the face and it has a prescription lense with bifocals attached to the inside of the mask lense that take up more room. In fact the bottom of the bifocals (the lense is extra thick there) actually just touch my checks - to give you an idea of how low of a volume it is.
Now since I know how to fill my mask up and I have a cooking measuring cup with ml’s on it, I should see just what the volume of my mask is.
