I love that it integrates with my Facebook page so we can easily communicate about our products to new customers and offer them special promotions! It's also very user friendly in terms of adding items into campaigns as well as customizing how they're displayed through tabs/sections within their dashboard.
The only thing I dislike is the lack of options when you go over 100+ people being added at once (which happens pretty often!). That said though, this isn't much different than any other program like MailChimp or AWeber - there are plenty others out there if you don't want all those extra bells & whistles but just simple features such as autoresponders. If you have no previous experience using programs like these then make sure someone who does assist you along the way because things aren't always intuitive! We've been able to get more conversions by having conversations directly from facebook posts which helps us turn potential leads right away.
