Well, perhaps I was too negative. As I mention below, and as the others have said, the look is pretty good. The heatmap image is pretty cool which is why I wanted to click on it and see it change. So let me do that!

Also, I did want to see how it actually worked, but I don't want to sign up and install stuff for that...so that's why I wanted a live demo.

I think you should drop the "completing with Google Analytics" angle too. Even if it's true that you're better, no-one will believe it. Why not show how you integrate with it instead? If people are using both and realise themselves that they only need your product, then that's good enough.
