I got this cutting board as a Christmas gift, and it broke in half by mid-March. I never put it in the dishwasher and occasionally conditioned it with mineral oil, so I'm not sure why. It hadn't even shown any signs of weakening-- just set it in the sink one night after using and when I went to wash it after dinner, it was in two pieces. Too bad - the board was a perfect size for cutting vegetables.
We bought this as a Christmas gift for my mother and two months later the cutting board is broken in half. They used it regularly for fruits, vegetables, and meats. For a cutting board as thick and expensive as this one, we thought it would have lasted years! Very disappointed by this purchase and now looking up warranty information.
