I like how easy it is to use in conjunction with our video analytics solution - we can easily link all of our data together so that we have a complete picture of what's going on across our network.
The software also has some really good features around user engagement as well which makes it very useful. It would be great if they had more robust reporting options available but these are not too difficult to create yourself once you know where things should go. We're using this primarily to track ad viewings (both TV & digital) as well as website traffic.
