you guys are missing the point.
this is not a diagnostic tool.
as part of my work, i evaluated this product as well as many others.
in fact, we still have it installed in one of our workers cars.
the fact that this products connects to the OBD port, doesn't necessarily mean it is a diagnostic tool. sure, it will read and report some basic fault codes, but the main goal of this products, it to improve safety and fuel efficiency.
it records trips, fuel consumption, accelerations and harsh braking as well as speed.
based on that, it creates some sort of a score. (very similar to the progressive snapshot).
the app is very very nice and has a lot of options for reports and notifications. it is also integrated with the
If This Do That app. very cool by itself.
you can create notifications, set rules, save reports to Google docs and many other cool features.
the question to the OP, is what you expect it to do for you?
