My experience with elica claude kitchen chimneys was good. I used it when I was living alone and I do not have any idea about chimneys but my nabour had a chimneys so they helped me to know how its works and its usess. Its works well and does not allow any smoke inside and keeps your kitchen tidy. Its also has a LED light that helps us to cook with good light. It has all the qualities that one look for in my chimney. So after my experience with thus I would like to recommend it to everyone as it will make life easy in cooking and cleaning.
