I bought Joomsharebar 2 months ago, and yesterday I found a problem with the face book like display. Actually it is my Joomla template's problem, but I still got the help from Roy, a very nice support guy who helped to solve all my problems quickly. I have used several similar components before, but Joomsharebar is the best. It is a very powerful tool for your web site and will fit all your needs. Definitely it is worthy to buy, and I have no doubt to give it 5 stars in my rating.
