The Bao Hui we bought has been used for 3 years, at least there is no problem now, unlike what Jiake Arrow Horse OK Silver Star has a severe oil leakage. After half a year's use, the effect is such garbage. We need to find a big company to produce it, otherwise it will kill us. Maybe it is produced by a small workshop. Can the quality be guaranteed? I was introduced to buy this and that before, and I bought a bunch of rubbish. Later, it was introduced by a friend of a clothing factory, and it was really worry-free to use.
