Andreani Pro Impact polymer suspension spacers

I came across the Andreani Pro Impact and find it interesting. Reminds me of the Formula Nepos polymer volume spacers. These replace the hard plastic volume spacers and fill most of the volume of the forks air spring. I am thinking about trying this on my 21 Fox 36. The kits are comprised of different densities of foam to change the feel of the air spring. Because they take up a lot of volume, one of the selling points is that you can use much lower air pressure. "... The consistency given by the polymers will permit to use a less inflating pressure of the fork positive chamber (on air forks) or to use a spring with less elastic constant (on spring coiled forks) maintaining same forces as static level."

They describe the technology as
"The PRO-IMPACT system is born to allow to easily tune MTB front forks, from 32 to 36mm, by optimizing their functionality according to the different terrains and riding styles. This kit – the result of years of studies on the interaction between air and polymers – permits to modify the progression curve and the fork dampening speed in compression and rebound, and to have a more constant functionality of the fork during high intensity and prolonged over time uses. The PRO-IMPACT main feature is the fork air chamber volume dynamic reduction that permits to have a dampening that cancels any kind of vibration you might have on handlebars, maintaining the correct bicycle setting. The purpose of this product is to increase the riding comfort and maintain the tire in constant contact with the ground, increasing grip and handling. "

Anyone try something like this? Price is not too bad to give it a try and since it's foam, it should not damage the air chamber.
