It worked fine for me but not without a couple of stumbles, which I suspect are server related rather than any issue with the plugin itself.
It took me a few tries to move everything. On the first attempt it only imported tags a some images, but no posts, pages or comments (and no error messages). I ran the import maybe 6 times in total and each successive run imported more each time until eventually everything was imported. So if you have this issue, just be patient. Everything will import eventually.
Given the plugin cost $0, I have no complaints!
