An employee at the MITSUMI factory in Shandong, China shared some information on the bilibili website.
First this is information about the factory where he works. Qingdao Sanmei （MITSUMI ）Electronics Co., Ltd. is a Japanese-owned enterprise, formerly known as Sanmei（MITSUMI ） Electric Co., Ltd., which was established in May 1992 and registered as Qingdao Sanmei Electronics Co., Ltd. in September 2010. The registered capital is US$35 million, and the total investment reaches US$100 million.
Here is my translation of his reply
1.The tf card slot has not been cancelled! ! ! If the back of the device is facing up, you can see it on the right side of the bottom of the U-shaped bracket by opening the bracket.
2.This is about the new pro controller.There are new colors of gray and black. There are two more gl and gr keys on the bottom, and an additional headphone jack.The back buttons I use are located at the inside of the handle legs, and the curvature of the button design fits the surface of the handle. Just like the car's fuel tank cap is flush with the body. I feel it's easy to accidentally touch
3.About the screen.Extremely black borders, don’t have any illusions about screen-to-body ratio, lower your expectations.Personally, I feel that the frame is larger than that of OLED. But narrower than the endurance version
4.About quality, production environment.The new pro controller feels very good and is more delicate than the 1st generation. However, I don’t know how the quality control is. Many of the newly opened assembly lines have a large number of new people working on a temporary basis. There are few old employees. At the beginning, screws were missed, buttons were missed, threads slipped, the paint surface of the button shell was scratched, and the buttons rebounded and became sticky. Various questions. The squad leader was so anxious that he was holding everyone in his mouth. It's getting a lot better now. The basic quality inspection found any faults. I'm afraid something might slip through the net. After buying it, check to see if there are any scratches on the handle and rocker. The right trigger button is most likely to stick and not bounce when pressed. Try it.
