Works well, nice overview of messages to be deleted and their matches. Thunderbird has been duplicating messages in my Sent mail folder recently, which is why I wanted this addon. I didn't notice the "ignore sent messages folder" that was checked by default, but once I changed it, it worked. (Note: right-click on the folder you want to check -- I didn't see any instructions to do that.)
