Mr. Ou has recently encountered a problem, because the customer has specially customized a fast rolling door, the door gap is much larger than the previous gap, so the filament length of the brush has also changed. Because it was the first time to purchase a back strip brush, Mr. Ou did not hesitate to place an order with brush length change. As a result, after receiving the goods, he was surprised that the filament of the brush could not stand up and could not achieve the sealing effect.

Mr. Ou was annoyed by this because the supplier did not know the purpose of the product and the effect that Mr. Ou wanted to achieve when he placed the order. Mr. Ou felt that they were not responsible for the customer. Later, Mr. Ou found AOQUN Mr. Wang. After receiving the consultation from Mr. Ou, Mr. Wang first learned about the specifications of the brush that Mr. Ou had purchased in the past. Secondly, Mr. Ou made the measurement of the data of the door seam and finally decided to use 100mm total. Combined with the characteristics of the filament, and the effect that Mr. Ou wants to achieve, AOQUN changed the diameter of the filament from the original 0.15 to 0.3 mm diameter, and provided the sample to Mr. Ou for confirmation within 3 days.

Through Mr. Wang's professional recommendation, Mr. Ou quickly felt the professional and caring service of the AOQUN, so he immediately determined to order 500-meter back strip brush.
