I like that it's not just for mobile networks but also includes fixed line as well (though this isn't always supported).
Having to go through multiple apps makes life difficult if you have more than one device or are using another program at once - so make sure your requirements match those of other software solutions before buying! We're solving problems with our current client data collection methods by providing real time analysis across different devices/networks which would previously only be possible after hours when we had access into their systems via VPNs etc..
