I think Durametric is great for an indy shop or a very experienced mechanic. I think it is less useful for average Joe Porsche driver because it does require a significant level of understanding when using it. DIY mechanics with less experience often get confused and misinterpret the data. For them (and me) a simple pocket OBDII reader works great. If I need deeper diagnosis, I take it to a trusted shop.
