A genuine ELM327 chip by itself costs $ 30.00, add price of the cables, enclosure, etc and you can see that there is no way you could get an original ELM327 for that price.
Now the seller could also have developed their own firmware and gone that route but it seems they claim it's a genuine ELM chipset, so I am interested in hearing from someone who actually bought one of these if it indeed works as advertised, better yet I will buy one of these and report back on what I find out, if it ever shows up at my door that is
