You say Vgate is reliable. I'm guessing many on ebay that say Vgate aren't really Vgate. How do you know which are real?
Is Vgate a real company or just another made up Chinese brand? If you google it, it just goes to obdinnovations.com, which is just a reseller, who also sells the same $1 V2.1 junk that's on ebay, that many have problems with.

What about this one?

This review says it doesn't have an ELM327 chip:

FYI, this review seems to be by the poster in on this thread (rogersride).
So it seems Vgate is not a good brand.
What about BAFX? Is that just a company putting their brand label on the same cheap Chinese fake ELM327 units?
What about these?
