Generally speaking, these TVs are products from regular channels and come from various well-known TV brands. However, due to the particularity of TV products, some key factors need to be considered before purchasing.

Finally, it is recommended to choose regular channels and platforms when buying a TV, such as Tmall and Taobao under Alibaba. Before purchasing, you can carefully read product descriptions, user reviews and other information to make a wise purchase decision.

In short, TVs on Alibaba are available for purchase, but you need to choose the right brand and model according to your needs and budget, and pay attention to product quality and after-sales service.
