"Lanflow is the easiest and best network diagramming tool I've ever used!!! For network mapping Visio and the other packages I've worked with are too complex and hard to learn but your software was a perfect fit. Within ten minutes I had a great diagram with labels that was clear and to the point. And with the Object linking and embedding it made it easy for me publish my diagrams to the web or share them with my colleagues. I've been looking for a product like yours for a long time... it makes it easy to make very complex diagrams without even reading the manual! That can't be said about CAD, Visio or any of the overpriced products on the market I've used."

  "I found Lanflow to be perfect for preparing my Cisco Certification course. It is SO easy to learn and use. The notation is in itself useful and attractive, but the real clincher is that it lets my students design LAN/WAN networks using the same notation that's found in our course book Designing Cisco Networks. I recommend everyone download the free trial of this wonderful design tool."
