5 stars Excellent in its simplicity

Far from the other limited, commerce-oriented, counter-intuitive popup plugins, this one is simple, entirely configurable, good-looking, and above all unlimited. Define as many popups as you need; design their content as if they’re posts or pages, fully WYSIWYG (even with shortcode support); choose which self-defined popups you want to use on each page, on as many pages/posts as you need; design exactly when and how you want them to popup, including hover and hyperlink; customize the appearance for each popup or clone them for uniformity. This was exactly the popup I was looking for, and creating popups with it much easier than I’d expected.
