I was really impressed with the interface. Very pretty.

However, I couldn't accomplish anything else with this program except logging into my FTP site. File transfers fail and I wasn't able to upload a single file to my site.

I dragged my files into the window, Flow populated the window with my file names and then most of the files just disappeared from the window. The files that remained in the window just sat there and did nothing.

As usual, don't pay for software that doesn't work. Use the trial first. I'm glad I did.
