Users appreciate the WordPress plugin for its ease of use, simplicity, and functionality. They find it particularly useful for quickly integrating the Slick JS carousel, converting standard WordPress galleries into attractive sliders, and saving time compared to manual integration. The plugin receives praise for its neat, bug-free performance and incredible support, especially from the author. However, some users encounter issues such as lack of compatibility with Jetpack and missing mobile responsive breakpoints. Additionally, the absence of clear instructions and occasional short code inconsistencies are noted drawbacks. Despite this, the flexibility and efficient integration within the WordPress workflow are highly valued.
