Users appreciate the OMGF Pro WordPress plugin for its excellent customer support, notably provided by Daan, which is often quick, responsive, and goes beyond expectations. They also value its effectiveness in optimizing website speed by loading Google Fonts locally, which reduces external requests and improves GDPR compliance. Many find it easy to use and beneficial for making websites faster and more legally compliant. However, some users experienced issues with compatibility, especially with certain themes and older PHP versions, and believe that key information should be more accessible in the user interface. There are also concerns about the free version's limited functionality.
