It's such a brazen ripoff that they even call it a Retrotink in the last description header. Maybe a copy/paste error?
I like my Retrotink 2X, but I have the old firmware with the audio issues and there is no practical way for the end user to update firmware. I haven't contacted Mike Chi, so I don't know how painless a firmware upgrade would be. For now, I just run the audio into my soundbar, so the Retrotink is video only.
I think a Retrotink 2x is a great option, especially since the new units from Mike Chi should have solved every issue that I've had.
