Review on OBD2 Scan Tool Diagnostic Professionals by Eric Nelso

Finally I tried to verify that this scanner works and found that it doesn't work, at least not what I thought it should do, which is the clear codes. When I plugged it in, it didn't go past the logo screen, it went to the screen described in the manual. I reconnected it after a few times but same result. Finally I went to the next step, got to the code screen and tried to delete them but it didn't work, I tried the suggestions in the guide but to no avail. I'm not sure if this thing is broken or if it's a scam and these things just don't work anyway.
