I actually post on a forum that a vendor for that product sells on and it is a good product overall. Now I dont have one personally, I will get one eventually and I do have a scanner and tuner. However, I love to document and track fuel mileage, pretty anal about it actually. This tool does that really well and can be customized some.
So from that perspective, its a good tool and to me would be personally worth it. From our perspective (from a 3800 owner) in the light of the tools we have available to us, it may not seem like a good thing. But, consider that fuel mileage is usually the first place trouble with your car shows up at. Any change in operating conditions (like temperatures, fueling, intake, friction) are going to show up quickly in fuel economy if you track it closely enough to know what your car normally does. The D.I.C. isnt quick enough.
It is an all around good tool for daily use when you dont want to hook up a laptop, dont want to buy an Aeroforce gauge, etc. Its there, can check and clear SES lights and track your mileage pretty accurately.
So if you compare it strictly to what we have available to us, it sucks, if you think of it in terms of it daily benefit and for the purpose it was designed for, its a pretty handy tool.
