I just want to say that I have been very please with this company in general. I purchased Broadcast and attempted to place it in a very complex site. I think that most people get extensions and expect them to work right out of the box in any site with any template and with any number of other extensions.
More than anything, it's important to rate an extension on the companies ability and willingness to help you work though the inevitable issue that will arise. This is such a company.
They worked very hard to make their product work with my site and even with the addition of custom work, they came through. This is a great extension and I'm happy to leave a good review for it. You can see it working at BizAds.us!
