When using the notebook computer at the destination, use it to compile the long code of the AC adapter. I use it again and again, but it will stop steadily without changing every time. Even when wiring work is used for temporary fastening, even in a narrow and dark place it is easy to see the color is white and thick. Of course, not only temporary fastening, but it is tightly fastened permanently. Although it is mainly used indoors, I am satisfied very much because it can be used any number of times (over 100 times of relaxation) without discoloring color.
