This a pretty neat product that you insert into a beer bottle to keep your beer cold and allow you to drink out of it at the same time. You put it in your freezer and when you're ready to drink, you put it in the bottle and can drink right through it. The downside (and this may be because it was the first time I used it) is that it has a strange taste that effects the taste of the beer. Also, it didn't really make the beer any colder...but that could be due to the massive heat-wave we're currently experiencing.
