Lifesize Video Conferencing Review

My company uses Lifesize for call-in weekly manager and sales meetings. Feedback has been very positive, managers have said they now don't need to travel to a remote site for monthly meetings (saving my company money and travel time). My HR department uses a Lifesize unit for interviewing prospective new hires. The feedback from HR has also been extremely positive. They use to use Skype and ran into all sorts of problems with [dropped calls] and freezing video. It's also saved time weeding out employees who may not be a good fit for our company.
