Anybody used one of these things? They look pretty good or is it just a jip and it doesnt work? The theory of it does seem legitimate and sounds like it would work?

Any opinions or info would be great! thnks guys!

There have been quite a few threads on this, do a search for Powerlung and there is a lot of info. I don't know of anyone who has got a dramatic improvement in freediving ability by using one.
