I like that they have an easy system for creating leads and tracking my progress in each of them.
They are also very flexible with scheduling as well which is great because we aren't able to do this ourselves at our own pace or time! There really isn't anything I dislike about their service other than perhaps it would be nice if there were more options for lead types so you can find people who may not be interested in your product but will still need some type of solution. Give them a try when you're ready for something different! We've been using them now for almost 2 years and haven't had any issues yet. Lead conversion rates has increased dramatically since we started working with them.
