I bought this chimney one month ago, And I have very bad experience About it. This chimney is very noisy you couldn’t on eat more than five minutes. I couldn’t stay in the kitchen for more than five minutes if the chimney was on. The dealer said that it is an automatic chimney, so when you use the mode you have to face some noise, but it was a very noisy chimney Compare to other chimneys. Whenever my mother needs to on the chimney, she puts earplugs in her ears. I could also listen to the noise of this chimney, from outside of my home. So whenever you are buying a chimney just make sure that the chimney is less noisy. It is a very irritating sound.
