A customer of Dennis of the Australian Rolling Door Manufacturing Company reported to him that there were a lot of small black spots on the top and sides of the rolling door installed by their company recently, and the root of these small black spots was the brush door draft stopper they installed to the customer not long ago. The customer also asked their company to provide a reasonable solution and requested to reinstall a new brush door draft stopper.

With trouble, Dennis immediately began to search the Internet for a more powerful and secure brush door draft stopper supplier. He noticed the brand Aoqun on Google. After carefully browsing Aoqun's website, he felt that Aoqun's overall strength is good, so he sent us an email.

As soon as he received his email, Stacy, the salesperson, immediately discussed the solution with the technician. First of all, we asked Dennis to send the product with the problem. After testing, we found that their brush door draft stopper was not made of 100% pure nylon glue filament, but other materials were mixed in it. Stacy informed Dennis of the situation and explained: "Poor quality wool is easy to melt at a certain temperature, and the brush door draft stopper is frequently used, so there are so many small black spots on the door." Dennis exclaimed, "If you use it earlier With your brush door draft stopper, there won’t be so many problems.” Next, we not only provided samples for comparison at the first time, but also provided relevant material inspection reports.

Dennis sent an order for 20000 meters four days after receiving the samples. He said: "We are looking for a professional supplier like you. From now on, all orders for brush door draft stopper will be handed over to you."
