The GUI is easy to understand, and even when troubleshooting, it is very simple to get the right information. We have only been using this product for about 3 months, but we are already seeing great results. There really isn't much that I dislike so far. It has everything we need and we love how easy it is to use. If you can find someone who knows what they're doing, they can set up this program quickly. This software was not designed with novice users in mind, so make sure you know your stuff before installing. For us, our network team has been able to see trends in data usage, as well as being able to easily block out specific devices from accessing the internet during times of high demand.
