Perfectjammer 2022/01/13

A staff member of a car rental company told me that Does Copper Block Cell Phone Signal can't be bought, sold or used casually, but now it can be bought casually in the market, so it gives some criminals an opportunity. Yesterday, I visited the electronic market. In the electronic market at No. 500 Qiujiang Road, many shops on the first and second floors have "information jammers" for sale, and some shops even put up advertisements on the walls. We pretended to be a buyer and communicated with the merchant, and the clerk recommended two products with different power. Among them, one is only the size of a cigarette case, for use in the car, and the asking price is 160 yuan; the other is a silver-white metal box with 7 antennas, which can be used in an area of ​​200 square meters, 560 yuan. The manuals of the two instruments are in foreign languages, and there is no text label on the product. Proposed to test first, the clerk readily agreed. Then, I put my phone on the counter, the clerk powers up an Cell Phone Jammer instrument, and after pressing a red button, the display lights up, indicating that the instrument is working. After a while, the mobile phone received no signal at all and could not make calls. The clerk also said that there are more powerful GPS satellite positioning devices that can interfere with the car. "Aren't you afraid of being investigated by law enforcement agencies when you sell this?" the reporter asked. The clerk replied: "No one cares, we have been selling for many years.

After turning around a few shops, I found that the Does Copper Block Cell Phone Signal sold is basically the same. The owner is not shy about its role, nor does he ask the reporter for the specific purpose of purchasing the equipment. When asked about the manufacturers of these instruments, most of the businessmen Wang Gu left and right. As far as he is concerned, some say these machines have no brand", while others say "we are just sellers, we don't know about production", or simply say "made in Shenzhen". Who is buying and using them? This kind of equipment? In the interview, a clerk said that most of them were purchased by schools and companies. Some schools bought dozens of them at a time, and some companies purchased them in order to prevent employees from making calls during work. Another clerk said: "People who gamble also buy more, and put the equipment in the casino to prevent someone from 'making money' with mobile phones. "How about online sales? In Alibaba and JD.com, you can find related products, and the options are diverse. In product promotion, all of them emphasize powerful functions and good shielding effects, but no merchants propose to purchase related products. Unit certificate, or identity certificate.
