I really like this Addon, the main reason is that it is complete in functions for advanced features in a website, but also it has gorgeous designs. I already have other addons, but they always miss something I need, or the design is not complementary. Ironically and luckily, Exclusive Addons has features and designs that others don't have.
I'm using it on a couple of websites, and the responsiveness and functionality are smooth; there are no side effects on the load-time. So, if you are into web development as a job, are an agency, or need a great tool to enhance your site, Exclusive Addons is for you! ;)
