I'm in the cooktop business! Never lie! Always tell the truth! Red Sun is better than Wanxi! But the red sun is to do infrared experts! But there is a big disadvantage! It's that infrared is a kind of stone, so it can crack when used for a long time! But, Mr. Owner, Mr. Owner! Please be careful! You might want to take a look at Wanbang! Wanbang! Specializing in infrared, this manufacturer only produces infrared and does nothing else! Specialized! Secondly, his infrared rays are made of materials harder than steel! The flame is really great, and the fire is big! It saves gas! It's really good! I suggest you look at this brand of gas appliances, this manufacturer does infrared! The infrared is even better than Red Sun's! Infrared's the boss! It's just that Red Sun's business practices are better now, that's why it's hotter! You don't have to give me any points! But I really recommend you to take a look at Wanbang! I'm not lying! Wobang's burners are durable, really! I'm not lying! You don't have to buy it, but you can check it out! Look at the infrared burning flame of Wanbang, you will know what is good ！！！！！
