It's very easy to use; it is also safe when using as you are able to create multiple profiles with different names which makes things easier for me in terms of privacy and keeping track of my files. I do have an issue where sometimes it will freeze up or crash but other than that everything has been great! The only thing i dislike about this software is how expensive its gotten recently (maybe due to increased demand). If your looking to share documents without making them public then airborn might be what you're after. You can make sure your sensitive information stays private by creating separate accounts for each person who needs access to file sharing capabilities.
