It seems like a good start for a new component coming up. But I think there are still several features missing. E.g. there is no function for recurring events, no way to customize the appearance of dates, no front-end editing, no access control, no way to duplicate events, no possibility for multiple-day-events, no administration for the calendar's templates and the html- and css-structure are quite clumsy (but that's the case with many J!-extensions). Yet, it is very simple to use. I think the mentioned aspects are essential for a good events-component, so I can only rate this one average.
PS: I find it astonishing that after more than one year with J!2.5 there's still no fully working and easy-to-use free events-component. I've never had any problems to find one for former Joomla-versions. What has happened?
