Just discovered that my 4th stone was broken and returned to woot by ups without ever making it to my house.
I have been issued a refund and a form apology. While this stone fiasco (am I allowed to call it that?) may not have been widespread, the folks, who wrote about their experiences here, seemed to have had breakage on multiple shipments. Surely this cannot be called a coincidence or a unique event. The only way to explain it is, "if you keep on doing what you've always done, you keep on getting what you always got."
