HiFiBerry Measurement Microphone for DRC?

[walter-]

I am looking for a microphone for Digital Room Correction at home, and saw the HiFiBerry Measurement Microphone for 65€:

USB measurement microphone | HiFiBerry

HiFiBerry published a short comparison here: https://www.hifiberry.com/blog/measurement-microphones/

Does anyone know more about the mic, can recommend it, advise against it, compare it with similar products (e.g. MiniDsp Umik-1)?
Proposals for alternative microphones are welcome.

I haven't seen any measurements the HifiBerry one. https://www.audiosciencereview.com/...ment-microphones-what-is-the-consensus.33589/ has a post comparing the calibration files for a large number of each of a few other models which should give some indication of how much variation there might be between microphones that are nominally the same.
