usb연결후 컨버터 폴더에 드레그앤드롭 하면 간단히 업데이트된다.

The only difference with Viltrox EF-Z is a plastic body (that one have metallic)
All other disadvantages of firmvare, unfortunately haven't corrected.
So if you use Canon 85mm F1.2 LII lens, functionality is OK, but apperture 1.2 will not be accessible with this adapter. Only 1.3.
If you use Sigma 85mm F1.4 lens, I don't recommend you to use this adapter. I.e. it's possible, but a lot of pictures where some person is relatively close to lens will be lost.
Techart TZC-01 functionates with this lens significantly better (if Techart is compatible with you camera, of course).
If you use Canon 135mm F2.0 LII - be ready to get a lot of problems at all. I haven't had time to test this lens with Meike adapter, but if it will repeat the problems with Viltrox, then be ready that you will not possible to get picture at all (problems of Viltrox with this lens: continuous fidget instead of focusing and often suspendings at turning camera on).
And with Canon 200mm F2.8 LII lens - functionates pretty well without mere problems.

Z9 펌웨어버전 4.10에서 3.01로 다운하니 잘되네요. 모든게 완벽합니다.
하지만 여전히 Z6에선 사진은 괜찮지만 동영상은 초점 떨림이 심합니다.
그래도 Z9에서 잘되니 추천합니다.

After the latest firmware update does not work with Z9

I can use this adapter with Canon EF200-400mm, EF100mm Macro to Nikon Z9. Although some EF lenses can not use AF, I am satisfied with the result.
