Too expensive
When my son finished building, I thought: this is a small set for the money. However, when I investigated, I discovered that this is a set that was never made for sale. LEGO gave away the pieces in another Harry Potter set. Therefore, you cannot find the set number in the LEGO app either. There is also another Monster Book of Monsters set, which was made for sale, with number 76449, which is much larger and much cheaper. So, I feel a bit cheated by the seller, as they are asking a very high price for a set that never had a selling price, so you cannot verify it.
