All good, are the industry's well-known brands, before the Spring Festival I bought a house with a friend, are replaced with the United States, but there is something that makes me very upset, my friend's home that was accidentally broken by the child's bottom plate, found that the cracked section is white, although the business to replace, but I have always thought that the bottom of the oven cavity is the same as the induction cooker of the black crystal panels, the United States of America's promoters also said that the black is good, and the result is to find that the black! Just a layer of the surface coated with something, and a friend's home to buy a different model but the base plate is the same, I took a closer look at my home and found that it is indeed different from the base plate of the induction cooker, induction cooker, black shiny, smooth and delicate surface, and microwave ovens do not have a glossy finish. This reminds me of the CCTV exposure of the United States some time ago, the surface of the purple clay pot is a toxic substance. But claimed to be made of authentic purple sand clay. Maybe the quality of the appliance part did not say, but in the future I never dare to put food directly on the bottom plate, and the surface of the layer coated with things do not sooner or later have to fall off. Other than that, it's not a big deal. Comprehensive comparison, Grantham is slightly better. From the present point of view, 500 yuan of products, the United States of America's cost-effective, more than 500 yuan Granz's more old-fashioned, product quality on the Granz is more real, product publicity, the United States is more pleasing to the consumer's favorite.
