Several years ago some friends used it.
Looks just like Soil Master Select.
Acts just like SMS- very dusty, lightweight (does not hold plants down well). They needed a diatom filter to clear the tank right after set up.
I have used Soil Master Select, and I like the look. It is high CEC, but it does remove the carbonates from the water, allowing the pH to drop. I fill the tanks very carefully to avoid clouding the water, so there is just a light haze for several hours or overnight.
