The ability to see all of my devices in one location, easily navigate through them and see everything I need to with just one click. Nothing so far! It's really easy to setup and use and it works great. They have recently updated their software to be more user friendly for the average person. If you're looking for a simple way to monitor your entire network, this should be at the top of your list. The only thing I dislike about this product is the price. Definitely worth every penny. Monitoring our network from anywhere in the world. It allows me to see everything happening at once, in just one place.
