Overall, the customer reviews for this product are mixed. While some users are satisfied with its cooling performance and quiet operation, others have faced difficulties with maintenance and operation. One user mentioned that the cooling function of the product was good and it immediately cools down when the code is connected.

The user also mentioned that the product tends to wobble a bit when a smartphone is placed on it. Another user commented that they were surprised by how quiet the product is compared to other cheap fans they have used in the past. They also mentioned that the cooling effect persists for a certain time, which is beneficial. However, they found it difficult to dismantle the fan for maintenance purposes. One positive aspect mentioned by a user is that even during the hot summer, their smartphone does not overheat when using this product. They also appreciated the customization options available. On the downside, some users found it challenging to operate the product when it is installed in a compact space, especially during extreme heat situations. In summary, while the cooling performance and quiet operation of this product are appreciated by some users, the lack of an on/off switch on the fans, difficulty in maintenance, and operation Constraints pose challenges for others.
