Generally speaking, it is reliable, but the price may be more expensive than Taobao, because they need to make money on these platforms, so it may be slightly more expensive. Buying a second-hand mobile phone will be more cost-effective than buying a brand-new one, especially mobile phones, which can be updated quickly. Once the new model is released, the old model will be greatly discounted. Especially if you sell a second-hand mobile phone that won't take long and is relatively new, the price will be lower. As for renovation or parallel imports, this is unlikely, because there are so many normal second-hand replacement machines now, there is no need to use so-called fake machines. If you buy it on this platform, you must make sure there is no problem before receiving it, otherwise it will be difficult to deal with problems in the future.
