I use it all day long as my daily driver for sending business documents in email or sharing them with colleagues who are not aware of our office suite tools/software (Outlook). The tool is easy enough to figure out without any training needed but can be overwhelming if you don't really know what your doing when first using this product so just do some research about how things work before jumping right in. Sending large file attachments through emails has never been an issue since we started using gorilla pdf now instead of having to send via FTP from desktop which was very time consuming process.
