The ability for us as marketers/admins is that we can see what our users are doing throughout their visit which helps in tracking of traffic flows through different pages within an app or website so it's great when trying new features out! I like how easy they make things look but sometimes there isn't much detail about why certain changes were made etc - this would be helpful if more information was given by staff members at Fluoro rather than just making assumptions from looking over code (which could easily lead me astray).
We have used them before though other services where not quite up-to speed yet either because some updates take time until all clients get updated versions too eek!!
