The suction cup won't stay or be attached to the dash: How to ensure strong adsorption of the suction cup? The bottom is a washable suction cup and pad. Rinsing and air drying the suction cup and pad after using it for a long time can restore their stickiness.

Before placing the product on the dashboard, you need to turn the button on, then press the product where you want it to be, and finally buckle the button. NOTE: The bottom suction cup maybe hardens when it is cold. this may affect the sticky function of the sucker, so we suggest you warm up the sucker pad from hot air blowing on it from the vent firstly, then stick it on the dashboard or other surface About the air vent: Only support horizontal and vertical air vents, not support the round air vent.
