01/2013 - I have it now for 4 months in use .... it is cleaned in the dishwasher and I can only say, properly! The quality has diminished in any way, that's still enough of blue in color. The white has gotten no food coloring and is still bright white. After so much use to knife marks have easily displayed in the board, I personally find not so bad as this, as I said, are relatively weak and it is alternating with two other boards, in daily use.
12/2013 - The boards is further described in use and continue in appearance and quality as in January =)
