Like I said the quality can vary greatly from batch to batch.Mine didn't just crack it almost broke in half.The cracks were big enough to stuff a ham sandwich in them.It cracked from the center all the way to the edge and through both sides and the cooling fins.Going from the center in the other direction it cracked all the way to the edge on one side and within an inch of the edge on the other side.
