I purchased this as a gift for my fiancé, only to find out he doesn't own a flask! Guess that's the next gift! This funnel is well made, with the narrow tube end being about an inch or so long, helping it stay upright in whatever you're pouring into. As some reviewers mentioned, it would be nice if you could tell/see when your flask is nearing fullness, but as I see it, this funnel is still a vast improvement on where you would be without one. I feel what sets this flask apart is the engraving of "don't miss a drop".
