The fighter in the garbage, my Supor pressure cooker has been used for 8 years. Because the quality door was afraid to use it, I changed it to Astar for one week, but I ignored it after the sale. Linyi Ginza said to change it, but it turned out to be the same one. After three months of use, the handle not only fell off, but also the silicone ring was broken. Other brands don't need to change for eight years. Astar is an advertisement. Never use it. You will regret it if you use it. I also bought Astar cookware online, so I might as well spread the goods on the ground. People who want to buy should be cautious.
