Title: OK but overpriced for limited functionality
Review: Yes, the 3120 is easy to use to retrieve error codes but BEWARE; it does not display live operational data, it is limited to just what is recorded in the vehicle computer memory. For only that, its price is not justifiable.My mistake in missing the distinction between the 3120 and 3130 in the on-line product descriptions. My mistake in buying the more expensive 3120 instead of the much more capable and less expensive 3130.
