I like that it is easy to set up in front of our users as well as behind the scenes for those who don't want to touch code at all! It's very flexible which makes it hard sometimes when you need something specific but not available out-of-the box (like we needed).
The support team has been great so far - they are always willing to help with any questions / issues we have had. We use this product primarily inside Salesforce because its built into their platform natively. This allows us to easily manage user access from anywhere without having to install anything else ourselves.
