Any opinions or issues re cabon fibre bottom bracket shells?

I've heard of some where the metal insert becomes loose in the carbon
shell around it. Other than that, it's usually around the BB (I.e.
where the large BB becomes tubes) that some crack, but not at the BB
itself as they are usually these days very oversize, as noted by
landotter.
