After the first usage and rinsing the timber was something rauhfaserig. However, I think that's normal, finally the board is "tied up" in many bamboo fibers. Once rubbed with cooking oil with 'nem paper towel, and it looked like new again. This is recommended anyway to regularly do to care so a does not fall apart the thing too fast.
Meanwhile, of course, cut marks on the wood are available. As far as I know that, but that happens with all wood cutting boards when they are not just made of high-quality oak across the grain for hundreds of Euros.
Unfortunately, I have worked with it once on my partially wet kitchen countertop. It was about 20 minutes "in the water". I thought for a short time soo happened before nothing. Well yeah, this was a miscalculation, it has thereby moved promptly. Ok, a real surprise for me that was not now, it has annoyed me anyway, but was my fault. Wooden boards, they should never into wet grip! The Herstller writes separately that the board should only be upright, dried with the fibers vertically upwards, for precisely this reason.
(The wet actually came from the freshly washed off vegetables that I had placed on or in front of the board, not because I'm too lazy to wipe! ;-))
Since it has only a very slight curvature which still is not a problem for using. After 2 months of use, so I'm still happy and can express my recommendation.
