Query: Not a functional nut cracker.

My neice bought me this nut cracker for my birthday and had only purchased it after reading good reviews on Amazon. In the reviews, people had written that it not only looked nice but was also fully functional; this is completely untrue. It is a difficult task to crack any number of nuts and if u do manage to open any, without smashing your hand on the table, what you're going to get is a smashed up mess of shell and nut. Don't buy this product for functionality, and don't pack up the nut crackers just yet!
