I don't think you should apologize. I was, and still am interested in buying a Dtec heatshield, and I'm glad this whole conversation has taken place. The data seems to show that it helps in moderate temperatures. They've had some problems, but what I want to see now is how they handle them. This is the perfect opportunity for them to prove that they are either responsible members of this community selling a good product, or complete tools. I really hope its the former.
On the other hand, I should apologize for hijacking your thread. You have your heatshield, and you seem to like it, so there's no need to drag you into this
