Input:
I had high hopes for this cocktail shaker, but after the first use, I was extremely disappointed.  The lid does not fit tightly so you really have to hold it tight while shaking.  That is manageable, but the worst part is when you pour the cocktail.  The liquid gets between the two layers and spills all over the place.  I wasn't happy about wasting good vodka !  I tried it several other times with just using water, but had the same results.  This is going back.
