It will not be used. It is a product with a screwed and switch ON structure, but it lights up when the battery is inserted and the main unit is fitted. It lights up even though it is not screwed in at all, it lights all the way until it stops as it is. . . That is, there is no OFF. Sometimes it goes out because of poor contact, so I tried to carry it at that position. Touch is resurrected with a little vibration and lights up. I have no more words. I think that it is not a translation of solid defects because the making is also bad, I think that all of this is not wrong. Although I bought it for spare insurance, this does not even connect even until I arrange the next light. Completely garbage! I seem to have shopped mistakes.
It was smaller than I expected. Even if it is attached to the key of a car or warehouse, it does not become an obstacle. It is a much better thing than the 100 th thing, but it is a point that I wanted a way to change the switching method. Because I just bought and used it, I can not evaluate durability etc. I can not recommend it to others yet unless I do a job that is commensurate with the price.
