Cheap is on the one hand, electric pressure cooker safety is the most important, big brands such as Nepal, Jiuyang, etc., but are labeled production, not professional, quality problems, and expensive, the reference price of the United States of America 6 liters of computer 499, Jiuyang 528, Nepal 568, Chuangdi 418, Lebang 499, Rongsheng 436, the above prices are 6 liters of computerized, complimentary liner. I recommend you Rongsheng, the earliest production and research and development of electric pressure cooker, big brand, cost-effective, and then there is Chuangdi and Lebang. Professional production quality is guaranteed,
