The gold-colored flexible duct is a high-quality item. I used it to duct exhaust air from my cooktop. This flexible section is under our cooktop and is visible when the cabinet door is opened (pots and pans are stored there). Its bright gold color is much better to look at than the former dull galvanized ductwork that was replaced. In addition, because of its strength and flexibility, I was able to make two 90 degree bends to link the cooktop to the floor connector, eliminating bulky, ugly elbows. This is a nice connector for a reasonable price.
