it's true, HMDmediashare components are still under developpement and purchasing them wont avoid you (but if you are Lucky-joomlaLuc) to face little bugs with it. Although, Im rating it 5stars! Why? because the components are at the point other components are at also, if not more developped specialy with the RevenueManager component you get for free (other C didnt develop it).
If you are scared of the "bugs"...the HighWood media share forum will kill them in 24hours for you, with personal service and support. What would you ask for more?
If not convinced about it, the component is not made for you so simply.

Cheers people of Joomla! Cheers people of Earth!
