Dear friend,
Thanks for your message. Sincerely sorry for the inconvenience caused to you! No worry, I'm here to help you.
When you use the item, you may need to press the button down first. Then the item can attached to the windown firmly. Please see attached photo.
Besides, the factory said that you can add a little water to the sucker. It can make the car holder attached to the window more firmly.
If you not mind, could you please try it again?
Thanks for your understanding!
Hope to get your reply!
Coco:)
