The best part is that it has an easy interface with lots of customization options at no cost! I like how VDC can be used in many different ways depending upon your needs (monitoring/data collection vs performance analysis). There are some great add-ons you must try out including SmartView which allows me access any device from my mobile phone or tablet without logging into another system first - this was very useful during our recent power outage when we lost connectivity otherwise would have been impossible to monitor everything so quickly!! If there were more features available such as being able to see what's happening behind firewalls etc., then maybe things could get even better? We use visual center primarily because its free but also due to ease of setup & configuration within minutes compared to other products. Easy way to gather all sorts of information about devices connected to network easily.
