Soldering is a special process that is difficult for amateurs to judge whether it is good or bad. Even if the soldering looks to be done properly at first glance, if appropriate treatment is not performed, it will affect the quality, such as a decrease in joint strength and a weakness against aging. The handmade cables sold here are made by workers who have learned soldering skills and perform appropriate soldering. Please use it with confidence.
