There's moderate consensus that there's a theoretical basis that this material should be an interesting candidate for a high temperature superconductor but is not a favourable output of the recipe used to make it.

Additionally there are now 4 independent reports (including the original and a highly prestigious chinese university) of it exhibiting diamagnetic properties (with no theoretical basis for non-superconducting diamagnetism).

This is more than enough evidence to say that the most reasonable interpretation is a room temperature superconducting material that sucks and is hard to make.

Upgrading that to a high confidence claim that the original research is reproduced will take a few weeks at least, so no super excitent yet, but the claim is fairly solid.
