There are no gaps or holes - the wood strips are glued well.
The board has been cleaned by us at the very beginning with warm water and treated with about 2 tablespoons vegetable cooking oil. The board has taken up completely all the oil!
We had decided on this board because we suspect holding together the long wood strips longer than many wooden blocks which are arranged in a checkerboard pattern. In addition, bamboo is a tough and very fast Renewable wood - because we have a bad conscience, such as in oak and almost all other types of wood.
I really want to mention this is the back of the board flat and has no grooves or feet, and thus is also useful.
