I had an adaptor but sold it. As others mentioned, AF is slow and unreliable. If you are willing to use MF, it does give you aperture control and the IS in the Canon lens also works.

Canon lenses need phase detect sensors to focus well. Most MFT cameras don't have that. The EM-1 and G9 have PD, but not the cameras you mentioned.  I doubt that a more expensive adaptor can compensate for the lack of PD focussing.
