This is a product with "no bottom line" in design, which greatly crashes the "new moon model". When sitting and watching the clouds rise, I always taste Zen tea because I like drinking tea, which is the initial direction of the project. In fact, from a commercial point of view, it is also a failed work, because it did not meet expectations. In line with the attitude of communication and discussion, we will also send it out for everyone to have a look. The company's 17-year project, 18 years of investment model, and ultimately because of the high cost led to the lack of market, I would like to reflect on this. The high cost is concentrated on the mold process of the elbow part. In order to ensure the unity, the "nitrogen blowing" process is used. If the description is wrong and correct, the grinding tool has been ground in the grinding tool factory for 9 months. Finally, there is a logical confusion problem in the design of the circuit board. Although it is finally solved, the market is still lost, which is a pity.
