Not much info about this new name, so I dare to try it. I received LR-EOS adapter last night and mounted my Leica R 50mm on it, quality seems to be really high. I'll say it's equal or better than Fotodiox Pro. It's connected firmly between the lens and body. I didn't have a chance to take pics yet but will when I have time.
In case you wonder where I got it, below is the URL:
