The programmability is fun to use. I get direct access to the pipeline. I use it to correct a few things that our clients and servers don't like. So I do some on-the-fly corrections and a little hacking, and it works better. The tool is really easy to install, very light, and extremely fast. It requires low maintenance. I'm quite pleased with the product. It is easy to learn the product. It's all documented properly. The person who wants to learn the tool must know how to deal with such products. However, it is relatively simple. It's running well in our organization, and nobody needs to touch it. We haven't really touched any configuration in over a year as it's still working great. It has been running my same VCL code ever since initial deployment. It has been running stable since, apart from some minor optimizations here and there.
