I like how easy it was for me to set up my infrastructure. The documentation was very well done. There were no surprises when setting this up at all! We have a few VPNs setup to connect our different offices together seamlessly which works great with these devices too. At first we had difficulties getting everything working correctly but once we figured out what needed to be changed nothing has been an issue since then. This device can hold about 30 users (or more) so there isn't much space available if you need more than one server per person.
