FAQ

We would like to establish a long-term partnership with your company, or become your agent. How can we proceed?

We are very pleased to establish a solid and stable cooperative relationship with you. However, the establishment of a cooperative relationship requires mutual understanding and consensus between both parties. We suggest that you first contact our sales area manager or channel development department to arrange mutual visits and communication, discuss cooperation details, complement each other's advantages, and reach a win-win cooperation framework.

Are there any hard requirements or indicators to become your agent?

We believe that the goal of cooperation is a win-win situation, so we are confident that imposing any conditions and indicators that are inconsistent with this goal are useless. However, having good social resources, excellent market development capabilities, and corresponding technical and economic resources locally will give you a relative advantage in competing for agency rights.

We are preparing to undertake a low-voltage intelligent project for a certain building, and are currently selecting manufacturers. What technical support can your company provide?

Please carefully review the "After-Sales Service" page on our company website. We provide comprehensive technical support and service in five stages to resolve any technical issues you encounter while using our products, ensuring your peace of mind. Our services are generally free of charge, but specific arrangements need to be coordinated with our sales personnel.

How is the quality of your products? What is the return rate?

Unlike many OEM brands in the industry, Welbell is the original manufacturer of high-end building intercom products. Our products all adopt proprietary technology, advanced production processes, strict quality standards and quality control procedures, with an online direct connection rate of over 95%. Statistics from 2009 show that the repair rate of our shipped products is controlled below 0.8% and shows a downward trend year by year. In other words, in a residential area of 1000 households, the number of problematic indoor units will not exceed 8.

What is the price range of your products?

Welbell products are independently researched, developed, produced, and sold, eliminating the need for third-party technology usage fees and processing fees, resulting in a cost advantage. However, due to the use of military-grade core components, strict quality control, and provision of high-quality after-sales service, these costs exist, resulting in Welbell products being reasonably priced and competitively positioned within the industry. Products with extremely low prices often compromise on component quality, quality control, or after-sales service.

How can I contact your company for business inquiries?

Our sales team adopts a regional manager responsibility system. You can contact our various branches or offices and connect with the sales manager in your region. If you contact our customer service staff, they are not responsible for product sales but will quickly transfer your information to the corresponding sales manager, who will contact you proactively.
