Troubleshooting
| Issue | Possible Cause | Solution |
|---|---|---|
| Liquid is not staying cold for the advertised duration. | Lid not sealed properly; extreme external temperatures; insufficient initial cooling. | Ensure lid is securely twisted on and the gasket is correctly seated. Pre-chill the tumbler with ice water for 5-10 minutes before filling. Avoid leaving in direct sunlight for extended periods. |
| Lid leaks when tilted. | Lid not secured; gasket is dirty or damaged; flaps on lid not closed. | Confirm the lid is fully tightened. Inspect the silicone gasket for debris or damage; clean or replace if necessary. Ensure all lid flaps are firmly closed when not in use. |
| Metallic taste in beverage. | Incomplete initial cleaning; reaction with certain acidic beverages. | Wash the tumbler thoroughly with warm, soapy water and rinse multiple times. If the issue persists, try using a baking soda and water solution to soak the interior. |
| Difficulty removing or attaching the lid. | Lid overtightened; gasket is dry or misaligned. | Do not overtighten the lid. Ensure the gasket is moist and properly aligned before twisting the lid on. |
