This can't be generalized. Tik Tok has a lot of live products, some are small objects we see every day, some are big-name hot-selling explosive products, but the prices are basically not very high.
Every platform has good goods and bad goods, and you can't kill them with one stick. However, I suggest that when you choose a live room to buy, you must choose some well-known and officially recommended live rooms, so that the goods you buy can be more secure and the goods you buy can be guaranteed to be worth the money.
