If it works, I would wonder how sensitive the result is to temperature and pressure shocks. If it is very sensitive, this may be a significant limitation on practical applications. For example virtually all portable devices wind up going through much faster temperature shifts than that. And raising it above the temperature that it was designed to work at, even for a short time, might result in no superconductivity. That isn't to say that it wouldn't be a very useful substance to have. But again, we need to wait and see.
