    No documentation at all, unable to use it….

    Good solid product. You have to read the wiki page for the connections and use github code in the beginning. Support from the store is excellent. I achieved around 30cm with the included fat card. Buzzer is not included.

    Good range compared to other modules. Does require good quality power supply to reach its advertised 40cm though (the video in the description was run on 3xAA/AAA type batteries!) but even on a “normal” supply you will get ~20cm. I don’t know the exact range I get out of the cheap rdm6300 modules under comparable circumstances with the same card but it might be as short as ~2cm. So thumbs up for this module. Was also able to run it on 3.3V … range seems to be the same as on 5V (at least with a crap power supply).
