This is a popular CICIBELLA product on social media. Please read the product description! Authentic product * 5-way * Compact, so it won't get in the way in your bag or pocket! * PSE mark certified * Airflow can be adjusted in 4 stages to suit various situations! Product Name: CICIBELLA Silent 5-way Fan PRO Size: Approximately 169*81*20MM Weight: 132g Airflow: Low/Medium/High/Rhythm (4 stages) Color: Dusty Brown Accessories: Neck strap, USB cable, Instruction manual The strong airflow and multiple functions make it very convenient! I repurchased this product, but When the remaining battery is around 20%, the CICIBELLA unit may run out of battery while charging a mobile phone. It might be an individual product issue. The unit is clean as it has been used only a few times.
