Affiliated to Shenzhen Dingnuo E-commerce Co., Ltd., Kunzhan is mainly engaged in the production of cookware and small household appliances, and is also one of the professional manufacturers of stainless steel fashion cookware in China. The company's cookware production capacity ranks in the forefront of the Chinese market, and its stainless steel products rank among the best in the domestic market, and the products sell well in more than 50 countries and regions in the world.

The brand has a high market share in the low-end market, the price is cheap, and in general, the workmanship is better than other products at the same price, and the product quality performance within the brand is also linked to the price. Stainless steel bowls for one person are priced at 20 to 30 yuan. However, in terms of material, ordinary steel is used, and the product is not thick enough and is easy to burn. Due to production cost considerations, some products are made of a mixture of plastic shells and stainless steel metal, but the plastic shells are easy to absorb oil and have poor durability.

The quality of the 304 stainless steel bowl, which costs 59 yuan on Taobao, is better than that of the instant noodle bowl of about 20 yuan. The feel of the product is heavier, and the whole bowl is made of stainless steel, which is more secure in terms of safety and durability, but it also has some problems that may affect the use experience, because the processing process is rough, and the product will make a screeching sound when the lid is opened. Moreover, the lid of the bowl cannot be tightly closed between the bowl, so it is inconvenient to carry it out.
