I like everything about bandwidth controller. The UI is very clear, it helps me set my IP traffic correctly.The interface is also very clear and the support is great if you need help in using it. We can control our servers by setting limits to the amount of traffic they must serve per day. It works with both windows OS and Mac OS. So it's good because we can use it if we run Windows servers or Apple Mac Servers. It lets me see how much data each user transfers from our network per day so I know what they are spending their time doing online and which servers they must be accessing to serve their needs. Bandwidth Controller is a really helpful tool for controlling bandwidth for our small network. It's very easy to use and has a good interface. There's nothing bad about Bandwidth Controller. It's a really good software for controlling bandwidth and helps me to keep my students safe and use my bandwidth efficiently.
