The first and most notable is the feature that up to six participants can use ooVoo simultaneously which is great if you want to video chat with your friends or need to bring people from different locations together to take part in a meeting. It runs pretty smooth even with six users and offers a good sound quality.

Another feature worth mentioning is that you can record messages with ooVoo and send them to other users even those who do not use ooVoo. Seveal other features that I use in Skype for instance are also supported in ooVoo. They include the ability to text chat with one or more users, send files to someone and add links to automatically use ooVoo to contact someone from a website.

Best of all it is really free. No premium version, no advertisement, no hidden messages, popups.
