Ceramic LR

Does anyone have any experience with using this product, together with some proper LR?
Microbes could easily colonize it, but inverts could not. I would suspect that the aerobic bacteria would do better than the anaerobes (which are needed for denitrification) On that basis it is limited in relation to real rock. Inverts cannot bore into ceramics as they do in natural rock.
Nor would the ceramic rock contribute to or support the alkalinity as natural rock would do. That is another significant disadvantage in my book.
