Is the light transmittance of the neck-mounted endoscope poor?
It’s not good for the eyes; try to wear it as little as possible
A wealthy man wanted to buy one pound of beef and received three quotes: a familiar person quoted 39, a close friend quoted 38, and a stranger quoted 25. In the end, he chose the stranger who quoted 25. But they didn’t realize that the acquaintances only earned 1 yuan, while the close friends earned nothing at all ； A stranger who scored 25 earned 15! In the end, he found that the beef was fake! It not only tastes terrible, but it also causes stomach problems for the whole family… Jack Ma is right: it’s not that there are too many fake products, it’s that you’re too greedy… It’s not strangers who take advantage of you; it’s your acquaintances who want to give you the best! It’s just that you don’t trust me!
Yes, after all, there is a short circuit~~which blocks some of the light~~
