Users highly praise this WordPress plugin for its ability to clean up unwanted code left by themes, other plugins, and WordPress itself. They find it effective, easy to use, and lightweight, highlighting its user-friendly interface and extensive pre-made templates. Many appreciate its flexibility in managing and enabling/disabling snippets of code effortlessly. However, some users mention drawbacks, such as insufficient documentation, persistent nags for reviews, and critical security issues like virus injections.
