OK, Since Noob is pushing their new version of 292J with the one-and-only-correct ceramic crown - for horrendous price..
...and ~150 USD difference just for better looking crown?
The fact is Noob has made ceramic crowns while H-factory has PVD crowns and they are pushing their crowns into all 292 series regardless being correct with gen counterpart.
Sources say all 292J have PVD crowns, some add that latter part of J-series had as a test some ceramic crown.
Ceramic crown is a tricky thing - since it is only a ceramic cap on metal head of the crown. It is brittle AND, when metal head extends due to i.e. heat - ceramic cap can crack easily.
I prefer to stay with PVD crown on J-series, only pita is that H-factory crown logo is less nicely looking than on Noob's. BUT Noob's engraving is correct for ceramic crowns. Thinner logo (as on H-factory) is OK for PVD crowns.
