Rosetta Stone learning Greek is a phrase I coined from the search results of the Rosetta Stone course.
I have tried Rosetta Stone and I found them a) instruing b) boring. So, no bullshit, you might like it or might not like it. I say you try it.
Rosetta Stone learning Greek costs about $300 so it’s a bit expensive but I think you may get a refund if you don’t like it. Perhaps, you will like it. It’s not like there is another option for learning greek.
