What brand of invisible protective net is the best?

I know that this product was introduced to the mainland market from Taiwan Province Province in about 200 1 year. At that time, it was called "Ming nu" in Taiwan Province province. Later, people from Taiwan Province Province set up Mingnu Company in mainland China, and pushed this product and technology to the national market.

Nowadays, many products are imitated, and some of them make great efforts in marketing and have various means. You can search at will on the internet, and there are at least dozens of various web pages waiting for you to see. Among them, I'm afraid there are not two who really understand the principle and design of this product.

Of course, maybe the problem is to promote yourself.
