The hinged front glass cover is very unstable. After a couple of times already broke a damper mount. When brushing one has gladly times the glass in his hand. For recirculation mode, the hood drawn almost exclusively in a small area on the right. Exactly where the enclosed filter sits. The delivered as a replacement hood was even worse. Inside various plastic parts were broken. The entire hood partially dented. During assembly it is advisable to do something about vibrations. Otherwise, the vibration of the hood carries resulting on the wall or on the kitchen cabinets to unpleasant noise. The rear mounting holes on the base are not available. My tip: Dear spend a little more and choose another manufacturer.
