Quality control tests are performed at various stages and the final quality test before shipping is primarily to ensure accuracy and ensure no defects prior to shipping. We've got a team of quality inspectors who are all familiar with the quality standard in the industry and pay great attention to every detail including product performance and package. Normally, one unit or piece will be tested and, it will not be shipped until it has passed the tests. Performing quality checks helps us in monitoring our products and processes. It also reduces the costs associated with shipping errors as well as the expenses that will be shouldered by both the customers and the company when processing any returns due to defective or inaccurately delivered products.
