This product is lovely in appearance. Though it is poorly constructed of lightweight metal collar and a plastic aerator. Upon first use, when I grasped the metal collar and twisted to release stopper from the wine bottle, I heard the plastic crack. The second time i used the product,as I applied the cork to the bottle, the metal collar snapped and competely seaprated from the aerator. I expected much higher quality from a Zwilling product. My mistake!
