I've had this Boos Block for almost 5 years, and I've been pretty happy with it. I know some people aren't aware of how much oil the board will take in after opening. I've had it start curving, which I fixed with more oil.
Since then, I've purchased some smaller boards from local wood workers, and the results have been a lot nicer and cleaner.
Local artisans are more likely to have kept the board in good condition. Where something from amazon or some other warehouse retailer may have been sitting in a warehouse for a while and could potentially have permanent damage.
