So far so good, I've only used it once, but will be using it a second time this weekend. No leaks or anything falling off, but if something changes I will update.
I don't drink often but when I do I like to try different stuff, expand my taste buds, if you will. This is a great way to do that. I like that is comes with some recipes and an ebook with more recipes. As little as I drink this selection may last me a long time. I'd say if you don't have (or want) a lot of money to spend, give this a "shot".
