If you experience a water leak while using your cup, check for the following:
(1) The lid and the cup are not fully closed.
Please put the lid on again and hear a click, which means it is tightly closed.
(2) The straw cap does not completely cover the straw opening.
Please press the straw cap down on the straw opening again. When you hear a click, it is tight.
(3) Hot or warm drinks
Hot coffee or hot beverages can cause internal pressure to increase and produce moisture to escape from the vent. It is recommended to avoid shaking the cup vigorously when drinking warm beverages, please closed lids or straw cap to avoid the risk of scalding if the product spills.
(4) Water seepage through the vent hole of the groove
The design of the inlet and outlet holes must exist when drinking, otherwise the vacuum state will make it difficult to drink. Therefore, when the cup is shaken, it is normal for a little drink to seep out from the vent hole.
