Query: Split quickly

I received the 24x18 21/4 inch board as a Christmas gift. I oiled it regularly with the Boos oil and dried it after use. Despite all of my effort, it split in multiple places in less than 2 months. Another reviewer had the same problem. I agree that the quality of the manufacturer must have declined over the years since there are so many great reviews. I was really disappointed. I wouldn't reorder since I think the product is poor. It looked great when it arrived but sadly, it didn't perform nearly as well. Thankfully Amazon accepted it back and told me they would credit my brother's account including the shipping (the board is very heavy). I am not sure that they have done so yet.
