Pure crap
Pure crap. there is no sync between the Powerpoint plug-in and the web app, plus you can't import Powerpoint. So you have to export to excel, then import to the web version. The expert version is so slow it's completely un-useable. Unless all users are premium you get a water mark on the web app, and unfortunately even once all users are premium you can't remove it without completely rebuilding the project. Lucen obviously has put more time in to monetizing the product than making sure it remains a value added product.
