Doctors liked it a lot. Application is easy to install and is pretty intuiutive. There was a great support system in place. Had very little problems with it once it was setup/adjusted after major changes to network, imaging devices in use, etc.
Diagnostic image studies are masssive, yes, but This software writes so much data to local cache so frequently I suspect it caused premature HDD failure on my former client's PCs. It was not uncommon for them to write 100GB in a week.
Their site to site caching setup leaves a lot o be desired, but it was something they were drastically improving upon before I transition roles and stopped supporting the client that used this.
