It's decent. The enhanced version is better though, as it has access to a lot more parameters. You are still limited by the serial connection (and the mroe parameters you try to log the slower it gets) and the fact that it can't read load of over 100% and stuff like that though...but there aren't any *great* logging pieces of equipment available to the general public so.. I think i's OK
It does let you scan and clear codes.
