Is there a physical store selling nut projectors in Jining city?

Why do domestic LED projectors only have a short warranty of 1 year? If LED projectors really have a long life, why is the warranty only half that of famous brand products?

Why do world-famous projectors such as Sony, Panasonic, Epson, Hitachi, China BenQ and Acer all have two-year free warranty, while domestic LED projectors only have a short warranty of 1 year? If LED projectors really have a long life, why is the warranty only half that of famous brand products? Because the actual quality of domestic LED projectors is poor, the failure rate is too high, the technology is immature, the parts are poor, the production equipment is backward, and the technology is backward, these small manufacturers simply can't guarantee 2 years! ! ! These fully show that domestic small LED projector factories are timid, guilty and have no confidence in their own products! ! !

The actual life span of domestic LED projectors such as nuts, polar rice and cannons is 2000-3000 hours * * * * * * The actual life span of LED projectors such as nuts, polar rice and cannons is 2000-3000 hours. After 2000-3000 hours of use, the brightness of LED lamps will drop sharply, and it will definitely not reach tens of thousands of hours! ! ! The price of replacing LED lamp components is above 700 yuan! ! ! Bisogni, the high-brightness light bulb of Panasonic projector is still expensive! ! !

Let's take a look at the warranty period of the projector. Why do world-renowned projectors such as Sony, Panasonic, Epson, Hitachi, China, BenQ and Acer all have a two-year free warranty, while domestic LED projectors only have a short warranty of 1 year? If LED projectors really have a long life, why is the warranty only half that of famous products? Because the actual quality of LED projectors is poor, the failure rate is too high, the technology is immature, the quality of parts is poor, and the production equipment is backward, these small manufacturers simply dare not guarantee for 2 years! ! ! ! The warranty period is only half that of brand-name products, which fully shows that these domestic small LED projector factories are very timid and have no confidence in their products! ! ! If LED projection is really so good, why don't Sony, Panasonic, Epson, Hitachi, Toshiba and Sharp in Japan do it! ! ?

LED projection technology is the most advanced in Japan! ! ! Why don't the Japanese, who are the world's number one in projection technology, do it themselves, and BenQ, a famous brand in China? Now it's China Shanzhai Factory's turn to make waves! ! ! You know, it's all a trick of domestic cottage machines! ! ! Why can't physical stores in Computer City basically see LED projectors sold only online? Why? Because of the poor effect, I can only deceive amateur consumers who don't understand at all on the Internet! ! !

The physical store can't test the machine because the LED projection brightness is too low to see clearly, and the quality is too poor, and the failure rate is very high! ! ! Japanese, American, Korean, BenQ, China and Acer are fully capable of mass-producing LED projectors. However, due to the low brightness and short life of the LED projector, the brightness of the LED projector dropped sharply in 2000 hours, so it was not mass-produced. It is still in the laboratory research stage, and only small factories in China Shanzhai can use it to cheat amateur consumers online! ! !

At present, the world-famous projector with a price of 3,200 lumens at 3,000 yuan has a service life of 10000 hours. After 10000 hours, the brightness is still around 2,000 lumens. From a distance, it still kills any brand-new LED extreme meter and nut cottage projector! ! ! ! Domestic shanzhai: nuts, rice and advertisements are crazier than bombing the sky! ! ! But the brightness is still pitifully low, even less than 500 lumens! ! ! Also pretending to be the international standard of 3750 lumens! ! ! Why cheat consumers when there are only a few hundred lumens? ! ! ! ! The quality is very poor, and it broke down in less than a year! ! ! And the price is as high as 5000 to 7000 yuan, pure slaughter! ! ! !
