anyone used the RF-coupled Contax-LM-adapter?

Does anyone here have experience with the RF-coupled Contax to M-mount adapter? (so not the cheap non-coupled adapters!)

A few very interesting historic lenses have been made in that mount, that I would like to try on my MM.

Amedeo makes the best. If you shoot with mostly 50mm lenses- the internal mount version will focus to 0.7m.

I also use the external mount type adapter-

But- used layers of copper take to correct the cam for close range.
