So, found that one:
https://www.asicminervalue.com/miners/dayun/zig-z1

Is it a thing, or a scam like someone thinks?

It is also sold by https://www.asicminervalue.com/miners/dayun/zig-z1 , which is a known trusted website (correct me if wrong).

Could not find infos about the company or an official website tho.

Just some resellers like:

https://coinminingcentral.com/
https://prominerz.com
https://www.cryptominerbros.com
