Product review (2 stars): Bottom Layers Split
I loved this when I took it out of the box; the size and shape were exactly what I was looking for, the lid fit well, it was pretty and the price was right.

But whenever I heated it up I'd hear a strange cracking sound.  Then the fourth time I used it, it started making weird hissing sounds and I realized that the bottom layers had split apart and a little water had gotten between the layers. The noise was the steam between the copper layers... bummer.  I was able to ship it back and get a refund, but I'm not sure if I'll try this brand again.
