Okay, a number of people have asked me to give my opinion about this new claim of "The First Room-Temperature Ambient-Pressure Superconductor".

I am not a real expert in superconductivity, but I am a guy on the internet with opinions, so here we go with some early reactions: There are two things that jump out to me as seeming shaky:
1. The authors don't actually identify a critical temperature Tc, they only claim that it's "above 400 K". In other words, they can't make the "superconductivity" go away. So are you really sure it's superconductivity?
