Title: NOT dishwasher safe
Review: Purchased on the basis of a positive review by Cooks Illustrated. Out of the box it looked promising. After one wash it bulged upwards so that only the four corners are touching the counter top - at least it bulged this way, otherwise it would be useless. Instead it is just annoying. There needs to be a "hand wash only" notice with this board. I suspect that the cause is the dissimilar materials of the board and the dimpled non-slip backing.
