Some prices feel very different, but maybe everything is the same, all genuine. Personally, I think 3 and 4 should be the same. Generally, many things below 300 yuan on Taobao are basically imitations, but if you look at your 600-odd and 800-odd, they should be true, but the purchase channels are different. I think you'd better buy No.3, the price is ok, and the goods are not bad!
