Cosmic-Perfume review for USO: Ultimate Special Offers

This app was so promising... I added it to a theme from the same company and it did not work well together. I uninstalled the theme and reverted to a much less expensive theme (which offers much more) but the app still does not live up to its promises. There is absolutely NO SUPPORT. Not for the app and not for the premium theme. I have tried fixing the issues myself but there is not even good online documentation. Uninstalled and reinstalled several times. Several emails and tickets opened for over a week and ... NOTHING.
