Query: Excellent Baking Stone

In the 3 months that I've had this stone, I've baked more than two dozen breads, plus dozens of pitas, bagels and rolls plus a few pizzas. It heats quickly and keeps the heat throughout baking. It fits perfectly in the oven, comfortably holding two 700g breads, and cleans up easily. I can't say much about durability at this point, but in all other ways, this stone has performed very well.
