[Closed] Shimano 142x12 freehub issues - worth a punt?

Got some v cheap rims from Planet X yesterday. In the same spirit, I notice that SLX M678 hubs are super cheap in the CRC clearance.

However, there appears to be an issue with some of this variety of freehubs (both SLX and XT) basically disintegrating under load.

I've been running M8010 XT on another build with no issues, so was wondering whether the cheapness of the M678 is related to this unresolved problem, and whether, if I break the freehub, they'll be likely to send me something a bit more reliable from SLX M7000/XT M8000 series under warranty?
