Love it, I use mine with my Kitchen Craft Wine Decanter.. It fits perfectly into the stem of my decanter and the rubber outer-ring protect the glass from rubbing making it a great combination. Kitchen Craft 1.5 Litre Bar Craft Connoisseur Deluxe Glass Wine Decanter Our cheaper bottles of wine taste noticeably better! You can really hear the aeration process happing and taste a noticeable difference in the wine.
I found that my old glass twisted aerator broke very easily with cleaning, this is pretty much indestructible.
We got many compliments from our first wine night with friends.
