I smelled odor that was suspected around the kitchen in my house. First, I found a lead wire of an electric oven broken. Furthermore, I smelled another type of odor around a microwave oven, in which wires were heated very much. I bought them almost sixteen years ago. It's a time to change them both. I ordered new ones that are all made in China and are much cheaper than what were made in Japan and broken this morning. New ones are not so durable than those made in Japan, apparently. Now, many people speak up for the sustainable environments. However, goods and utilities are often broken and bought cheaper than before. I'm really doubtful of what the sustainable means.
