I bought it because I saw many positive reviews here. However, one of its major functions is to get sync of my google calendar. However, after connecting my google calendar, I can't make few alterations on the dashboard of Illumtori. So, I disconnect the sync between them, and I independently build up my calendar on the dashboard of Illumtori; nevertheless, it's not flexible to make many changes, such as only using my mouse to extend the time duraion (Google calendar can do so). The only solution is to connect my google calendar again, to make modifications on my google calendar, and then to get back my Illumtori.

This is supposed to be a tool to increase my productivity, but it does the contrary thing towards it.
