First of all, you should know that in our country, buying brand-new electronic products depends on luck, let alone being second-hand.

Liars are not necessarily, but the industry of electronic products is actually quite deep.

My little advice.

If it's the same city, I suggest you find a knowledgeable friend to see it. Different cities suggest starting with caution.

These days, even Taobao and Tmall are sometimes troublesome to defend their rights, not to mention idle fish.

Second-hand electronic products and online shop assembly machines are riddled with holes, just like what is said upstairs.

Since the subject is here to ask questions to show that he is not knowledgeable, my suggestion is: Xiaobai should be cautious when buying second-hand electronic products, and don't be greedy for cheap and suffer big losses. Although I'm not saying that this seller must be a pit, I really think that if you don't know how to buy second-hand electronic products and feel lucky, you can consider starting.
