The ease of use, ability to extract data from multiple sources into one place - it's like having an analyst in your pocket! I would love more support with customisation as well- but we're working through that process at present time so no issues there just yet :) Great product overall though very easy setup & simple interface which makes using this software quick without any learning curve required (which is always great).
We are able solve many problems by pulling information together here rather than manually entering all our contact details everytime something changes or someone joins/leaves etc..
