I have compared the prices offered by several factories, why some prices are high and some very low?

Each factory practices its own processing mode. Although the processing equipment is almost the same, the workmanship and sense of responsibilities vary greatly. Cost performance cannot be simply decided according to prices or scale. Any products without good quality and service are one-off deal and do not last for long. The price offered by JM is not affected by other manufacturers. JM emphasizes high-quality products only, and receives every customer with the fastest speed and the warmest services, in order to make customers become our regulars.
