Pricing was fair (if the tech worked), online chat support was responsive in answering simple questions, CM was fairly easy to set up
Tech was completely unreliable. We experienced countless complaints about the quality of our streams (audio and video). We had at least 2 occasions where the tech failed completely while we were trying to broadcast to 1000+ people. It was humiliating and we finally got tired of writing apology emails to our viewers and quit CM.
The answer from CM was always that it was our fault, never CM's tech or servers fault. We had our internet connections maxed out, had tech experts come into our facilities and check all connections and speeds, and they said our internet connections were smoking and there were no problem on our end. We ran multiple tests,rehearsals, and speed checks in preparation of our webinar events. The last straw was when we paid extra to increase our seating for a 1000+ for our big webinar, and paid to have a CM tech on call during the webinar in case there was a problem. Once we went live, the tech immediately melted and we could not broadcast. Our paid CM tech support was no where to be found for over 10 minutes as this nightmare unfolded. When they finally responded, they once again said the issue was on our end and there wasn't much they could do.
Since then we switched to a new webinar vendor. We have broadcast the same webinars, big crowds, same setups with this new vendor,, and amazingly have had ZERO tech issues. Our viewers responded that it was the best audio/video they had ever seen from us.
ClickMeeting was so promising in many other ways, but when it can't perform consistently well at its one job -- providing a decent broadcast experience -- we had to move on.
