I've used it extensively. Dense and durable it is. It will also eat your blades alive and tox you into your effing grave.They sell it premilled as deck wood; no milling, only end cutting and making bisquit pockets for the specialized (plastic; separating spacers at the ends and screw hole in the middle) bisquits.
My contractor decided he wanted stuff milled out of this stuff. I start a dark mustard/ochre/brown piece through the saw, and this roostertail of bright chartreuse dust comes up from the cut. I'm wearing the mask and goggles, and within ten seconds my nose and eyes are burning, itching . . . any of you turkey necks ever sneeze three times inside the mask? Euw!
Hard, dense, variable in color and character, abrasive to blades, okay but generally bland in appearance, toxic, unstable, difficult to glue, de Poinz hate it.
Amen,
