+## Consider native alternative
+
+If you don't need to support legacy browsers and don't need the advanced features this package provides, consider using native datetime input instead. It's more accessible, adds no extra weight to your bundle, and works better on mobile devices.
+
+```tsx
+<input aria-label="Date and time" type="datetime-local" />
+```
