There are quite a few who have, including Greg Reverdiau from Pilot Institute. Everyone I know who's flown one like it. I'll be getting one soon as well. It won't see much time in the air, but if I need it for a certain gig, I'll have it. I'm just hoping they upgrade it to be able to use the RC Pro for our Mavic 3s.
I do want to clarify something though. You don't say where you are, but the statement that it's "the correct weight too to fly wherever you want" is not correct in the U.S. All airspace laws apply to all drones regardless of weight here. The only thing the Mini 3 is exempt from is registration if you fly strictly recreationally.
I know there are EU rules that apply to this as well, and they have weight exemption for certain locations. But even they don't consider the Mini 3 to be able to "fly wherever you want".
Might want to double check your local rules.
