Not really sure why this is so expensive when you can easily get a reader that does all the same stuff for under $20.

^ Could be that it uses a real ELM327 chip instead of a knockoff Chinese clone chip... not that the Chinese clone chips don't work, BUT many of the readers using them don't even do all OBD2 vehicles despite their claims. This has nothing to do with whether it's a real or clone chip but rather other cost cutting measures on some cheaper readers.
