It is very easy to use. I have been able to set up my new business phone system in less than 30 minutes. The software is very user friendly. I also love how it works so well over wifi. We are still learning all of its features but we can see many uses already. They provide great customer service via email or even by phone if needed. There was only one time that they did not respond within an hour after contact was made. Otherwise this has been excellent! Nothing at this point. This has helped us so much because it allows our employees to work from home when sick instead of having to wait until we get back into the office.
