Looks really cool and does keep your beer cold - haven't tried anything hot in it. It fits one beer exactly, so I probably could have used an extra small bit of space at the top. It was a touch expensive, but definitely gave off the cool feature. Somebody did mention that they break easy - I bought 2 sets and so far, so good. I wouldn't be inclined to throw them in the sink with other dishes, I treat them as I do my wine glasses, which is find by me. Again, a very neat item and we're glad that we bought them.
