I like that all my records are organized by patient, which makes it easy when i'm searching through them later! There is nothing really bad about this product so far because we haven't had enough time with our accounts manager/client services rep yet (she's been great though).
If you're looking at an email client similar but better than outlook then consider using these products together as they integrate well - meaning everything gets pulled up under one account list instead if having several subdomain emails pulling different data sets etc.
