Spirit Aerators

I haven't used them but I've heard they open up Whisky a big quicker than air time.

I have one for wine and one for whisky. I know the wine aerator enhances the flavor without giving it excessive time to breathe. I've only tried the whisky one a few times and haven't really made a decision, it seems like it does make the Bourbon taste like a bottle that has been opened longer. Thought more would have an opinion on this. I know I'm not the only one who has tried them.
