Thousands of Nintendo 3DS console users recently said they had headaches and dizziness after using the Nintendo 3D Naked handheld game machine 3DS. But Nintendo does not return it. 3DS was listed in the UK on March 25 and was listed in the United States two days later. Prior to the IPO, Nintendo warned that the 3D game was not suitable for children under 6 years of age, not because the screen was too bloody, but because its 3D effect affected the development of children's eyes. Sundeep Tailor, a 27-year-old player Sandip Thelles, said he and his son had only played 3 minutes and had headaches and dizziness symptoms, which were less than 24 hours before he bought 3DS. But when Taylor took 3DS to the local game store to prepare for the return, he was refused by the shop side. Finally, Taylor returned 176.99 pounds to the 3DS, but the price was 30 pounds less than the price of the 3DS. Taylor was frustrated by letting consumers bear the costs associated with the deal. "I lost some money in 24 hours," Taylor said. I believe there are many people in the same situation. Nintendo said earlier that users could adjust the 3DS 3D effect to better enjoy the product. As for the symptoms of the player, Nintendo said the feeling would not last long and suggested that the player should not play for more than 30 minutes.
