I bought two of these boards just over a year ago. When I received them I was very happy with the quality until now. Just out of warrenty of course one board has begun to seperate a glue joint allowing it to start warping and become a bacteria trap. Given the boards are only warrentied for a year I will have to trash it and buy another. I went to the Michigan Maple web site the manufacture of these boards and read the tips on buying boards. Their advice is when buying an end grade board you should purchase a board a minium of 31/2 inches thick to avoid cracking and warping. In my opinion and others the end grain is the only kind to buy so I will purchase a 4 inch Boos board next.
