Works well but a little confusing at first.
It works well, but it is confusing to use and the lack of a Help file makes it more so. It also lacks options available in other software like the ability to save settings between sessions. I would also like to be able to simply over-write the contents of a folder with the compressed files but if this is possible the means are not obvious.
Having said that, with a little use, it becomes intuitive and finding an efficient workflow is not difficult. The results are impressive and it does everything the description says it does. I have a lot of pictures to upload to a photo site with a relatively slow internet connection. Now, what used to take hours or have to be left overnight can be done in half an hour or so.
