The best thing I like about this product is that it was easy to use as well as its customer service team. It also has great features which makes one's life easier when conducting business meetings or seminars via video conferencing. Nothing at all! This tool really helps me conduct my work in an efficient manner by using their services. If you are looking for a cost effective way of running your business efficiently then definitely give them a try. They have helped us organize numerous conferences and seminars. There were no issues nor complaints regarding any aspect of working with them. We highly recommend them because they provide quality services without charging exorbitant amounts of money. We used them to host several seminars and conferences where we conducted training sessions to employees on various topics such as accounting, marketing etc. As mentioned above there weren't any problems faced during those events so far.
