The best thing about this program is it's ability to get all kinds of information easily and quickly within seconds. There are so many features which I have never used before such as firewall rules. It is very fast and reliable especially if you have multiple connections running at the same time. I would say that it's only good in terms of speed because it takes too long to open files or save files. I highly recommend this product to anyone who wants to learn how networking works quickly and effectively. I use it to track my computer usage including websites visited and other general internet activity. The features are very useful in our daily work. It's easy to use because there isn't much configuration needed once you get used to how things should look like. I have not found any problem so far but maybe i've been using this product only since few months ago :) Great tool! We're solving problems related to traffic management at my current job (we provide internet access).
