The level of detail available in the data is very detailed and the ability to drill down to the level of the transaction is extremely powerful. Very easy to use and implement. The customer support is really good. I have no dislikes. Napier really listens to their customers. They are always willing to discuss any issues and implement changes as soon as they are felt to be necessary. The fact that Napier is adding new functionality all the time is a huge plus. Napier provides a lot of data in an easy to use interface.
