I like that it is easy to use with very little training required. It's not perfect but has been working well enough that we haven't needed another solution yet. In our case, there are some limitations in terms of storage space. We're using this as an additional tool to augment our existing WAN monitoring product so if you have other tools or products already in place then this may be overkill. However, since our primary focus was just capturing packets from multiple locations within the organization, this did exactly what we wanted and nothing more!
