Is TV shopping credible?

How can I put it? I used to think that shopping on TV would be more secure than shopping outside the mall, and it was credible regardless of the price. But then something made me afraid to think so. It is enough for a master Hu not to touch the pot. You can know it by Baidu. There are also some things that have been exploded by netizens recently. The camera you mentioned, in general, may be for children to play with, and it is estimated that you can shoot something, but the effect is probably not flattering. And I am particularly tired of exaggerated tone and wording in TV shopping. I don't like it or believe it anyway.
