We have been using their service since september '08 and our experience has been terrific. We called them a few times when we signed up for the service because we needed help with setting everything up and to make sure we were doing things right. Since then I've called occasionally to ask basic questions and the people they've got in support have always been helpful and nice to speak with. Based on the customer service, they deserve 5 stars. But the service itself has been perfect the entire time. What we get is great, especially saving some money off our phone bill when compared with our Verizon service.
