I ordered the plain stone extractor hood a few months ago. My old hood was unfortunately defective. I chose this cover because it looks very good and modern. A friend helped me hang. First, the cross braces come to the wall. Screws were to fix them. You have nothing buy more. When the heavy lower part depends, the veneers have to be pushed on it. That was a bit hard and we were afraid the surface to scratch it. Now that everything is installed, I'm really excited. The extractor hood has been as I expected it. She takes very good. The exhaust goes outside. Looks very classy, because there is no right buttons. Unfortunately, the power button reacts sometimes not so good, dry hands to make it work better. So I can live with that. It's really a bargain and looks great. Perfect for the modern kitchen.
