Supor is the largest R&D manufacturer of cookware in China and the second largest in the world, and the first listed company in China's cookware industry. The market share of its pressure cooker, wok, frying pan and other products ranks first in China all year round, and the market share of small kitchen appliances such as electric pressure cooker and rice cooker is also the top three in China. In terms of exports, Supor's products are sold to 41 countries and regions, and since its establishment in 1994, the development speed has been very fast.
 
Supor focuses on cost performance, cheap and good quality has almost become synonymous with Supor, its price is almost less than 600 yuan, especially the aluminum alloy pressure cooker, the lowest is only 139 yuan, in the horizontal comparison with other low-priced brands, whether it is materials, quality control, after-sales have very obvious advantages.
 
However, the cost reduction will obviously have a certain impact on the quality, such as the Supor stainless steel pressure cooker uses 304 stainless steel instead of 316 stainless steel, which has a more advantageous price, thus pushing the price to about 250 yuan. Although 304 stainless steel is not inferior to 316 stainless steel in safety, it is slightly less resistant to corrosion, that is, the life may be slightly shorter.
 
In addition, the Supor pressure cooker cannot be compared to international brands in many aspects, the lid is not very finely made, the design is not very reasonable, and some liquid will condense on it during cooking and depressurization, increasing the risk of burns, and it cannot be removed as quickly as the WMF. The polishing/brushing of the outer layer of the pot and the identification of the capacity of the inner tank are not excellent, and there is a sense of roughness visually, but such a price obviously cannot put forward higher requirements for this.
 
YW2xS1 series is a series with excellent cost performance, depending on the size of different models are also slightly different, the price is around 350 yuan. As mentioned before, although its own design and workmanship are not particularly outstanding, but the most valuable thing is that it is still equipped with a pressure visualization system at such a price, which can see the internal pressure status in real time, and the high-pressure feedback has a great auxiliary effect on the timing of opening the lid, and it is easier to detect when the pressure relief hole is blocked, which greatly improves the safety of the pressure cooker.
 
In terms of capacity, YW2xS1 has three specifications of 4.0L (YW20S1), 5.2L (YW22S1) and 7.0L (YW24S1), and the diameter of the bottom of the pot is 20/22/24CM, which corresponds to 1-2 people, 3-4 people, and 4-5 people.
