Input: This is a worthless aerator. Does not fit into the wine bottle securely. As soon as you pour the wine it falls out into your glass, spilling wine everywhere. You can try to shove it further into the bottle, due to increased resistance and not wanting a glass bulb to shatter in your palm. Terrible design. Terrible product. Please do not waste your money like I did.

Does not fit into wine bottles. Does not function as it should.
