I've been using ACF since it was first released. This is a plugin made for developers. ACF has revolutionized the way WordPress sites are built these days. A core component for any site using WordPress as a CMS. Clients love using the interface that ACF provides. The author, Elliot Condon, is completely devoted and produced the the most needed plugin ever made for WordPress. ACF has went above and beyond awesome and deserves 6 stars, not 5.
