The problem of counterfeit goods in the electronic market has always been a cancer that disturbs the market order, while ordinary people are the direct victims of counterfeit goods. Recently, Wuhan electronic market staged a fake MP3 farce. A Founder brand USB flash drive MP3 in China is cheap and sells well, but it is also a copied classic product of Chaohua Digital ZARVA MP3-55 1 1. Because of the price, few people have talked about it. It has been proved that this is a fake, and the buyer is miserable. Fake goods have no manufacturers, no service and maintenance, and quality problems. In addition to poor sound quality, machines often crash for no reason.
This incident reminds our people that in the mixed market of MP3, it is better to be more careful and choose MP3 with wide eyes.
How to identify genuine MP3?
Many consumers pay more attention to function than brand when buying MP3. In fact, only by purchasing qualified products from regular manufacturers can consumers use them with confidence.
At present, some small southern township manufacturers with strong speculative psychology in the market get the molds of big factories through some improper channels to produce small quantities of products, use poorly decoded, digital-to-analog conversion chips and defective flash memory chips, and then flood the market at extremely low prices. Due to the crude production equipment, the product quality cannot be guaranteed. This product not only has a short service life, but also has no after-sales service.
Experts in digital industry warn consumers: After getting MP3, first check whether there are three things in the box: MP3 merchandise, product warranty card and instruction manual. If these basic things are not complete, then the next identification process is unnecessary; Secondly, confirm whether the purchased MP3 is a fake by the body code. Because each MP3 has a unique code, the easiest way for us to identify MP3 is to confirm the serial number of the machine by phone. Generally, larger manufacturers have 800 service hotlines. Call the service hotline to find out the truth. Third, check the MP3 body, including whether the accessories are complete, whether the machine is damaged, and whether the sound quality is up to standard. Finally, remind consumers that thoughtful after-sales service is an important criterion for consumers to choose MP3. MP3 produced by domestic small factories basically has no service guarantee, and once consumers buy it, there will be endless troubles. As far as domestic professional digital manufacturers are concerned, Chaohua digital service is the most priority, and the policy of "replacement in January, one-year warranty and lifelong maintenance" is adopted.
In short, when purchasing MP3 products, consumers must go to formal channels and shopping malls to recognize brands, products and services, and beware of being deceived.
