I like that you can easily create custom fields when needed.
Also, it has an easy to use interface which makes using this program very intuitive for new users as well as experienced ones. There is nothing really i dislike about it but if there was one thing id say maybe its how long it takes sometimes in loading or responding when sending emails through their platform! Its great because of all our contacts are kept organized within one place so we dont have any problems remembering who works where anymore!
