Hi Lilian, thank you for taking the time to share your feedback. We're sorry to hear that the product did not meet your expectations. Our High Speed Cold Compress Fan is designed with a press-to-activate feature to ensure safe and stable use, especially during travel or when stored in bags. The button may feel slightly firm at first, this is an intentional design to prevent accidental activation and ensure long-term durability. Once the fan is activated by pressing the button, you can slide up or down on the control to smoothly adjust the fan speed to your preference. If you press and hold, the fan will speed up more quickly, allowing you to reach your preferred setting with ease. We’ve also shared a usage video with you via email for further reference. If you have any other questions, feel free to let us know, we’re always happy to help. Thank you again for your support and feedback!
