I like everything about it but best of all is that its free! There really isn't much to dislike, if you are looking for something better than other MDMs out there then this one will be right up your alley.
Nothing at all specifically so far as being able to do certain things with our sales teams more efficiently or anything else in general though we don’t use any custom fields either which would have been nice. We just wanted an easy way to manage contact information without having two separate applications (like when using another application called "my info").
