Never tried it. Would be interesting to see some results if you or anyone else has examples.
Just from experience though and with the reception of Muse, don't expect an overwhelmingly positive response because those automatic coding tools are still behind most coding capabilities and typically provide bloated code.
It's not free..After showing you the generated theme, they ask a subscription of x$ in order to allows you to download the zip...Nothing is REALLY free.
p.s. i noticed another thing...the preview theme it's not a generated wordpress theme because the urls of the menu refers to my original site location :-)
