The email plugin is by far my favorite piece of Clearslide, but it is still very buggy and makes my outlook crash. Even so, the amount of time required to search for presentations and attach them has been reduced.
The platform consistently seems half-baked. The content search is not prescriptive as promised, but instead, pulls content that is most commonly used. The call/web conference functionalities have some of the worst quality (sound, video) that I have ever seen. The new UI is only slightly better than the last, which is nothing special. The best part about CS, in my opinion, is the email plugin, which is helpful, but makes my outlook crash most of the time. When CS is coupled with other Outlook plugins, my email freezes consistently. Our company also has ExecVision, which syncs with CS, but never properly pulls the call details. The new plugin for SFDC is also incredibly lackluster, especially the notes portion, which strips all formatting. Like I've said, the idea of CS is great, but the execution is half-baked.
I'm sure that CS has a good price point for the functionality, but the product is half-baked with full of functionality issues. I would recommend looking at other platforms with improved functionalities and a content platform that truly enables sellers, rather than simply pushing the most "popular" collateral to the top.
