I have Elica FS 301BK LTW 60 cm Chimney and it is a long durable product. I am using since last 3 year. Till now I don’t have any issues. Only I have to clean the oil filter in two weeks. But the function of the chimney is very good. It does not produce heavy sound too and sucks the smoke very well .Its usage is very easy where there are push buttons to vary the suction .It also has LED lights which helps to see the cooking item more closely. It does not require much maintenance cost. You will be free from the tension of oil spreading inside the kitchen. Go for this product if you need a stylish designed chimney in your house with a low level noise and great suction power to remove the smoke from your kitchen. I strongly recommend this product if you want to live tension free life.
