+## Why Use This Module?
+
+When compared to other free alternatives, this module stands out because:
+ - **It's really fast:** With an average global latency of just 25ms, it's one of the fastest options available.
+ - **Effective localization suggestions:** It works well to suggest changing the user's country or language/currency based on their location, making it ideal for enhancing the user experience.
+ - **No browser location sharing required:** Unlike some other solutions, it doesn't require the user to share their precise browser location, ensuring better privacy while still delivering accurate information.
