We recently purchased Syncfusion to provide Word, RTF and PDF exporting within a new .NET application. The product was extremely easy to install and use. A problem was noticed with French characters for the RTF export functionality. I notified Syncfusion who confirmed the issue and promised the fix on a certain day. Incredibly I received an e-mail on the promised day stating that the fix was ready. A quick install and all was good. Fantastic service.
