I like how easy it is to use. It also has a lot of options for customization which makes it very useful when you have some specific needs or requirements. The customer support can be slow sometimes but they do respond quickly once you reach out to them with any questions. My biggest issue so far was finding someone who could help us set up multiple devices. We needed this because we were doing penetration testing. There is nothing about packet viper that i dislike at all. If you need an easy solution and have no experience setting up networks then this software will make things much easier for you. We used packets viper as part of a security audit we did where we had to connect several different types of equipment together to test their compatibility.
