They got the same effect that got everyone excited (half levitation) with a similar material that is ferromagnetic.
Considering that there is a lot of unknowns and randomness regarding the synthesis of LK-99, and that the half levitation effect can be explained by ferromagnetism, to me, it sounds much more likely that the original LK-99 is a ferromagnet rather than a superconductor. Simply because ferromagnets are common, and a room temperature superconductor is an extraordinary claim.
I'd like to be wrong, but for now, it doesn't look good for superconductivity.
