It was extremely easy to setup and to get working on the site. It is very accurate in its data, it looks very cool and provides loads of options for display.
The best thing for me is that I when I had a couple of questions my email was quickly responded to with detailed information.
When asked to developed further plugins so that other components could be tracked they came back with a cost effective price and were helpful throughout.
So, yes, I am happy wth having paid for this item, it works, its easy to use and its well supported.
