I like how easy it is to use and all the functions are there. It's very customizable and has all the features you need. It also looks great and is easy to navigate with all the different tabs. I wish they had more customization options and that it was easier to add new fields or create custom reports. I don't think I could find anything that I dislike. I've been using this program for about 3 years now and have no complaints. It allows me to send out email campaigns and track my leads. This helps me to manage all my contacts so I know who needs what next.
