I tried it last year, but didn't find any presets that were effective and practical for voice disguising, and didn't have time to learn how to wrangle the low-level effects to do the same.
(To be clear, pitch shifting is trivial to reverse, so not what I would consider effective or practical for this purpose.)
It was easy to set up, though, and appeared to be better maintained than some of the alternatives. I might give it another try eventually. Perhaps some commercial audio plugins would help.
