Query: Slightly warped, cracked after a handful of uses, but other than that...

The board arrived slightly warped, but putting a paper towel under it solved that problem and I thought I had an excellent board. But then it cracked after less than five uses. I did not put it in the dishwasher or otherwise abuse it...to be avoided at least based on my experience.
