Hi,
Hazel works quite well since I bought it in 2013. Unfortunately something went wrong after upgrading to El Capitan. As it seems, a lot of users, like me, have the problem that OS X tags simple vanished after the upgrade. I use the tags mainly to let Hazel move a file from the desktop the folders specified by the tags.
As soon as I finish typing in the tags, hazel moves the file to its destination but unfortunately, and I think this is since El Capitan, all tags are deleted on the way. So the files gets to its destination but all the tags are gone.
