Carbonation stone experience (The Stone)

Have a question or want to show off your project? Post it! No Registration Necessary.  Now with pictures!

I am looking into buying a carbonation stone. I see one called "The
Stone" advertised at: http://www.homebrewheaven.com/the-stone.htm
It says the active area is 2" which is longer than some other ones at
1" however I am not sure about the quality of that 2 inches. For
instance, what is the pore size? 0.5 micron, 2 micron? and how
effective is this compared to other available stones? Is there a
manufacturers web site for this particular model?

Any one have experiences with this one or others? Care to share them?
Also, how much CO2 (flow rate) can run through this device. I need one
that can handle a gas flow rate of about 0.5 liter of CO2 (STP and 0
Deg C) per minute


Thank you for your assistance.
