Users appreciate this plugin for its functionality, ease of use and customization possibilities. It effectively adds a sale badge feature to WooCommerce, potentially boosting sales by highlighting discounts. Users particularly like its lightweight nature and ability to display savings as a percentage, enhancing the visual appeal of the discounts. However, some users are concerned about the lack of recent updates and the small size of the "Save $x" text, which they feel is not ideal compared to a more noticeable sale sticker. Overall, the plugin serves its purpose well and is particularly helpful for emphasizing sales on e-commerce sites.
