China's market sales of soccer, domestic and foreign brands appropriate diversity, and each brand style quite a lot, and even some manufacturers to provide customized services, printing exclusive personal or team graphics on the ball surface. For example, across the international and sports varieties of Adidas, Nike, Puma and other well-known brands, other countries brand KELME, Kipsta and other production input, as well as China's access to the Asian Football Confederation (AFC) tournaments designated for the use of the ball Molten, or in recent years, Conti, ANGO, ENTES and other local new-style brands. Each fierce competition at home and abroad in the soccer sports market, with its appearance and design, material quality, durability, comfort, and even price differences, each with different customer groups.
If the local soccer industry is to be sound, it has to start with the production and marketing of local soccer products. Among them, the newly created ENTES brand is a new soccer brand based in Taiwan and New Taipei, hoping that the local soccer can gradually become self-sufficient, so that it can grow into an international soccer brand in the future. However, while moving towards this direction, how is the quality of ENTES soccer balls and how are they different from other brands? The only way to get relatively objective and scientific results is to actually test the soccer products in use, so that readers can understand the value and positioning of ENTES among many soccer products, and thus compare the CP value of its products.
I. Long-term measurement of various activities in recent years
The author from the 2019 New Taipei City school tour to promote soccer, and 2020 so far in the North District school tour to promote soccer, with the Hwa Hsia University of Science and Technology and served as the Director General of the New Taipei City Sports Federation Soccer Committee Associate Professor Tsai Shang-ming led the coaching group, touring the counties and cities of the National Primary School and its kindergarten attached to the implementation of the activities to bring the memory of each participating children happy to play football, and to obtain the full support of well-known manufacturers, both at home and abroad. KELME, ANGO, Entex and other brands of No. 4 soccer balls have been used. In addition, the Football Committee of the New Taipei City Sports Federation has been handling the 108th New Taipei City Joint Football Competition from November to December 2019, and has continued to organize various tournaments in successive years, using No. 4 and No. 5 footballs of brands such as KELME, ANGO, Entex, and Molten, and so on.
The New Taipei City Sports Federation Soccer Committee's implementation team has used hundreds of soccer balls for more than 100 days and 60,000 minutes over a period of three years and seven months, and has accumulated a relatively complete record of each soccer ball's dosage, usage, and time of use:
During the 66,060 minutes of actual use, the longer each brand's soccer ball is used in the same scenario, the more it can show the proper rate and durability of its products, thus comparing the CP value of different brands of soccer ball products.
II. Kaifeng ball situation before the event was held
It is the New Taipei City Sports Federation Football Committee handles a lot of soccer promotional activities and age-graded tournaments at all levels every year, from May 16, 2019 to June 26, 2022, with a long period of time and a large number of footballs. This makes the author, including the New Taipei City Sports Federation Soccer Committee to undertake various activities, in the preparatory period for each activity for the manufacturer to deliver the new soccer ball, will be opened one by one to check the newly purchased soccer ball condition, including ENTES (ENTES) No. 4, No. 5 soccer ball, including a number of brands. Compared to the large number of soccer balls purchased by individuals and the long duration, it is possible to randomly compare the yields of new soccer balls from various brands.
For example, the New Taipei City Sports Federation Football Committee used 50 new KALME brand 4 soccer balls for the 2019 New Taipei City School Football Tour from May 16 to 30, 2019, and all of them opened with their skins intact, with the exception of one new product that had a defective air leakage problem. In the following year, the 2020 North District School Tour promoted soccer activities, switching to ANGO branded size 4 soccer balls, which can be customized with logo printing on the surface, and two batches of 50 and 30 new products, all of which were inspected and found to be flawless at the time of opening. As of early October 2021, the 2021 New Taipei City Joint Soccer Competition used six size 4 soccer balls from ENTES, and all of the new products were flawless; however, among the four new size 5 soccer balls, one soccer ball had a small flaw with a slightly skewed air hole.

All brands of new products after opening, in addition to the above table calculated the time of use, are placed in room temperature, indoor and intact storage. Since each brand of soccer ball itself has a trace of ash, to prevent the air pressure with the temperature, humidity changes in the rise and fall, resulting in excessive ball pressure problems, so the above new inflatable products are not obvious air leakage resulting in a lack of ball pressure, not included in the scope of this article of defective soccer balls.
