I just signed up for the service, so I don't have much to say for a review of the actual product yet (other than it was SO easy to set up and the UI is clean and intuitive) - but I DO want to call out how awesome their customer support is. I was able to talk to Marc, who was incredibly patient (and friendly!) with my countless questions before I signed up and then stayed patient with my immediate request to change the automatically assigned phone number I was given to a new one. It took about 2 minutes and I had a new number... and this as after only taking about 3 minutes to download the app, sign up for the service, and have an active account with new business phone numbers set up. VERY good experience already! Great job guys!
