I like that it has a very user friendly interface. It's easy for me as an RN/PCCN to navigate through the system. The training was excellent! They were able to provide us with all we needed to know about this product so that our transition went smoothly. We had been looking at other products but decided to go ahead with Doc Eng because of their customer service and ease of use. Not much dislike yet. If you are thinking of switching from another product make sure they have great customer support. As far as cost goes - we haven't seen any difference between using Doc Eng or not.
