I’ve tried a handful of other “Top” rated plugins but PMPro was definitely the easiest to implement. Everything worked as it was supposed to. That bundled with the fact that it’s free!! I don’t think you can beat it. I paid for additional support, and it was well worth it. The add-ons, plus the fact that you can use native WP plugins to add more functionality make this plugin truly worth using.
