I have only used electric pressure cookers before, but I have never used such pressure cookers that cook by gas. I just got it, but I don't know how to use it, and I'm afraid it's not safe to operate it by mistake. After reading the instructions and operating them, I found that the previous worries were completely unnecessary. The operation is simple! Therefore, it is recommended that you read the instructions before using, and you must pull the cooking regulator back before opening the lid. This is a process of pressure relief and deflation, so there is no danger that you will open the lid and deflate when there is still a lot of pressure in the pot.
