This is one of our favorite tools, it's very easy to use with its drag-and drop feature, plus you can customize everything as needed! We have been using this tool for some time now without any problems at all.
The only thing I didn't like was that sometimes when we're running a build in production mode (we don't do continuous integration), we get errors about missing assemblies which could be fixed by adding them manually. It would've been great if there were more libraries available for download or maybe an option to install them directly from within the application. Otherwise, no complaints so far, keep up the good work! We are solving website performance issues, increasing uptime, and reducing downtime while maintaining a high level of security.
