Nox1s,

I just spoke to K40 (JayJay) and he checked information for your state "MI" and there are NO Legal issues. The only states I know of from first hand experience are VA & Washington DC.

I also spoke to them about adding to there website state by state legality links. They thought that was a great idea.

Good luck, FYI we sell and have had tremendous luck with these units.

Regards.
